1. WHITE HOUSE:
Speculation rampant on second-term Obama Cabinet, but he may choose stability
If history is any guide, President Obama's Cabinet is in line to lose at least one of its top energy and environmental members should he win a second term this fall. Two of the 20 leaders at U.S. EPA, the Energy Department and the Interior Department under the nation's three most recent two-term presidents hold the distinction of staying on board for all eight years. One question that looms while Obama gears up for a hard-fought re-election battle, then, is whether Lisa Jackson, Steven Chu and Ken Salazar will enter the history books as a Carol Browner or Bruce Babbitt -- Clinton-era Cabinet officials who stayed the course -- or join the 18 others who departed sometime before the end of the second term.
