House lawmakers have already seen two of their senior colleagues fall to other members in contentious intraparty primary battles this cycle -- as Rep. Dennis Kucinich (D) lost to Rep. Marcy Kaptur (D) in Ohio and freshman Rep. Adam Kinzinger (R) defeated Rep. Don Manzullo (R) in Illinois -- so it's likely members still waiting to face off in the election this year are taking notes.

With new district lines in place across the country in the wake of the decennial reapportionment process, nearly two dozen lawmakers found themselves competing with a fellow incumbent to return to Capitol Hill in 2013.

Here's a look at each of the nine remaining member-vs.-member contests in Arizona, California, Iowa, Louisiana, Michigan, New Jersey, Ohio and Pennsylvania, along with the latest fundraising data released this week -- organized by state.

Arizona

The Grand Canyon State won't hold its primary contests until late August, providing GOP Reps. Ben Quayle and Dave Schweikert several additional months to snipe at one another in the Scottsdale-based 6th District.

The GOP freshmen ended up in the same district after Arizona redrew its congressional lines to accommodate the new House seat it picked up in the reapportionment process.

Republicans had urged Quayle to seek re-election in the more competitive 9th District, but the winner of the 6th District GOP primary is likely guaranteed election, and he opted instead to challenge Schweikert.

The Club for Growth rankled Republican leadership last month when it issued a public letter warning Speaker John Boehner (R-Ohio) and Majority Leader Eric Cantor (R-Va.) to remain neutral in the contest.

The group criticized Cantor for backing Kinzinger in his bid to oust the more senior Manzullo, as well as donations made by a super PAC operated by a former Cantor aide.

It likewise demanded that Boehner's leadership PAC match a donation it had made to Quayle's campaign, by making a similar donation to Schweikert. Federal Election Commission records show the PAC had not donated to Schweikert's campaign as of the end of March.

A spokesman for Boehner's leadership PAC and Team Boehner, the speaker's political operation, told E&E Daily in March that Boehner does not plan to endorse in the contest.

Quayle, the son of former Vice President Dan Quayle, leads the cash race, claiming $1.3 million to date after adding $390,000 to his coffers in the last quarter. Quayle had $972,000 in cash on hand at the end of March. He also listed a $14,000 debt, including a $2,500 loan he made to the campaign last quarter.

Schweikert trails closely behind, raising $1.1 million to date but adding a smaller sum of $250,000 during the first quarter. Schweikert banked $812,000 at the end of March but reported a $100,000 debt from a loan he made to the campaign.

California

Voters in the Golden State will head to the polls in early June to select their candidates, but thanks to California's new "jungle" primary system -- in which the top two vote-getters advance to the general election, regardless of party affiliation -- two intra-party tussles could continue into November.

Although California didn't lose any of its 53 seats to redistricting, two sets of Democratic lawmakers were prompted into showdowns after the state's new nonpartisan redistricting commission carved up existing seats.

Reps. Brad Sherman and Howard Berman are waging a top-dollar contest for ownership of the 30th District seat each calls home in the Los Angeles-area San Fernando Valley.

The new district is made up of about 20 percent of Berman's current district and 60 percent of Sherman's district.

Berman, a 30-year congressional veteran and the ranking member on the Foreign Affairs Committee, outraised his competition in the first quarter, pulling in $577,000 and bringing his total to nearly $3 million raised for the cycle. Berman reported $2.5 million in cash on hand at the end of March. He also had a $63,000 debt.

Sherman, who is in his eighth term, raised less in the first quarter but reported $4.1 million in cash on hand at the end of March. He added $202,000 to his coffers in the first months of the year, for a total of $1 million raised to date. Sherman also lists a $369,000 debt, including a $250,000 personal loan he made to the campaign.

Democratic Reps. Janice Hahn and Laura Richardson are similarly sparring over ownership of the Los Angeles-area 44th District.

Hahn, who won a special election to replace ex-Rep. Jane Harman (D) last year, emerged as the fundraising leader in the first months of the year after trailing Richardson in 2011.

Although both lawmakers continue to post significant debts to their campaign finance reports, Hahn reported raising $210,000 in the first quarter, bringing her total to $436,000 to date. She maintained $175,000 in the bank at the end of March, along with a $141,000 debt that Hahn's campaign has previously identified as related to her special election.

Richardson, whose debt has increased to nearly $450,000, raised $81,000 in the first quarter. She has raised $394,000 to date, banking $116,000 at the end of March.

The California lawmaker's debts include a bill of $213,000 to Shallman Communications for "communications consulting" and $98,000 to the law firm Perkins Coie for legal services.

Richardson revealed in November that the House Ethics Committee is investigating whether she used government staffers for political work.

Iowa

Redistricting in the Hawkeye State might have forced a GOP primary showdown between Reps. Tom Latham and Steve King, but the former opted to move into the 3rd District, where Democratic Rep. Leonard Boswell holds the seat.

Latham crested the $2 million mark in fundraising, after bringing in $399,000 in the first quarter. He retained nearly as much, reporting just under $2 million in the bank at the end of March.

The Republican lawmaker also shrunk his debts, reporting just $9,000 in outstanding bills, rather than the $30,000 he reported at the end of 2011.

Boswell continues to trail, although he increased his take in the first quarter to $214,000, up from his fundraising at the end of 2011. He has raised $880,000 this cycle and banked $644,000 at the end of March.

Louisiana

Republican Rep. Jeff Landry has yet to confirm that he'll challenge fellow GOP Rep. Charles Boustany in the state's new 3rd District, but most observers expect a duel to develop.

The Republican duo landed in the same district under the state's new congressional map when Louisiana lost one seat in the reapportionment process.

Louisiana's all-party primary is set for Election Day in November, with a runoff Dec. 1 if no one clears 50 percent of the vote.

Boustany continues to lead in the money chase, much as he did in 2011, reporting a total of $1.5 million raised through the end of March. He added $348,000 to his coffers in the first quarter and banked $1.5 million at the end of that period.

Landry, who was first elected in 2010, improved his fundraising in the beginning of 2012, boosting his total to the $1.1. million mark after adding $322,000 in the first quarter. But he still trails with $820,000 in the bank at the end of March.

He also lists nearly $26,000 in debt, including $25,000 in loans made to his campaign. He reported a new $5,000 personal loan in the first quarter.

Michigan

The Wolverine State lost yet another House seat in the decennial redistricting process, prompting an intraparty match-up between Democratic Rep. Gary Peters and freshman Rep. Hansen Clarke.

Peters saw his suburban Detroit district eliminated in the state's new congressional map, and he opted to face off with Clarke rather than challenge senior Democratic Rep. Sander Levin.

Peters continues to lead the money chase in the contest, raising more than double Clarke's take in the first quarter by adding $278,000 to his coffers. Clarke raised $115,000 in the same period.

Peters has raised nearly $1.5 million this cycle and reported $1.2 million in cash on hand at the end of March. He also reports a debt of $18,000.

Clarke has raised $615,000 this cycle, banking $564,000 as of the end of March.

Southfield Mayor Brenda Lawrence is also competing in the Democratic primary, but faces an uphill start with significantly less campaign cash. She reported raising $63,000 in the first quarter.

Former state Rep. Mary Waters has also announced her campaign, but the FEC does not list an account for it.

New Jersey

Democratic Reps. Bill Pascrell and Steve Rothman are vying to determine who will return for a ninth term in the House and who will be a lame duck after the June 5 primary.

The Garden State lost a seat in the decennial redistricting process, and Rothman opted to move into Pascrell's territory in northern New Jersey after the state's redistricting commission put his home into a GOP-leaning district held by Rep. Scott Garrett (R).

Environmental activists have already lamented the loss of one of the Democratic lawmakers, who have each earned identical 94 percent lifetime scores from the League of Conservation Voters.

Both candidates proved their fundraising mettle in the first quarter, raising more than $500,000 each.

Rothman reported raising $543,000 in the first months of the year, bringing his total to nearly $1.1 million for the cycle. He banked $1.8 million at the end of March.

Pascrell reported a slightly smaller but still impressive $514,000 haul in the first quarter, raising his total for the cycle to $1.4 million through the end of March. He reported $1.6 million in cash on hand.

Ohio

Rep. Betty Sutton (D) opted to take on freshman GOP Rep. Jim Renacci rather than challenge a fellow Democrat after the Republican-dominated Legislature divided her northeastern 13th District when Ohio lost two congressional seats in the decennial reapportionment process.

The lawmakers will compete in the new 16th District, which includes part of Cuyahoga County.

Sutton remains an underdog in the contest but closed the money gap slightly in recent weeks.

The Democrat reported clearing $1.2 million for the cycle after she added $391,000 to her coffers between mid-February and late March. Sutton maintained $784,000 in cash on hand at the end of March.

Renacci raised less during the same period, adding $293,000 to his account, but has raised $1.6 million this cycle. He banked $1.2 million as of the end of March but still carries a debt of $370,000 in personal loans he made to the campaign last cycle. According to his personal financial disclosure reports, Renacci, who owns a variety of businesses, is among the richest members of Congress.

Pennsylvania

In the Keystone State's new 12th District, Democratic Reps. Jason Altmire and Mark Critz are in a contentious battle that, for the winner, will likely result in a contentious general election contest.

The Democratic lawmakers are sparring for control of a redrawn district in the Pittsburgh suburbs and other southwest communities after the state lost a House seat to reapportionment.

The new district contains more of Altmire's current territory in the Pittsburgh suburbs but also has Critz's Johnstown base, which he won in a 2010 special election to replace the late Rep. John Murtha (D). Primary voters head to the polls in Pennsylvania next Tuesday.

Both candidates are claiming endorsements in the race, with Critz winning significant union support from the likes of the United Mine Workers of America, United Steelworkers and Utility Workers Union of America -- and most recently was endorsed by former President Clinton -- while Altmire has named several dozen local officials who have pledged their support.

Altmire leads the money chase, having raised nearly $1.5 million through April 4, according to his most recent campaign finance report. He banked $331,000 in the first three months of the year and reported $419,000 in cash on hand as of early April.

Critz has similarly broken the $1 million mark, reaching $1.1 million after adding $268,000 to his campaign in the first months of the year.

As of April 4, Critz reported $232,000 in the bank but also had $76,000 in debt. He made a $50,000 personal loan to his campaign in the most recent reporting period.
