From the NYT:
President Obama is reconstituting the team that helped him win the White House to counter Republican challenges in the midterm elections and recalibrate after political setbacks that have narrowed his legislative ambitions.
Mr. Obama has asked his former campaign manager, David Plouffe, to oversee House, Senate and governor’s races to stave off a hemorrhage of seats in the fall. The president ordered a review of the Democratic political operation — from the White House to party committees — after last week’s Republican victory in the Massachusetts Senate race, aides said.
This is useful for 2301 since it touches on party leadership and 2302 because it addresses one of the unofficial roles president's play: party leader.
