The Los Angeles Times examines how lawmakers who are up for reelection are factoring their presidential endorsements into their own campaign strategy:
Clinton forces are pushing back to convince superdelegates on Capitol Hill that Obama will have a harder time winning a bruising general election campaign against Sen. John McCain of Arizona, the presumptive Republican nominee.
Her allies argue that Obama is untested and will be dogged by controversies including the inflammatory comments of his longtime pastor, the Rev. Jeremiah A. Wright Jr.
Rep. Brad Sherman (D-CA), a Clinton backer, gives her a clear edge in electability: "Her minister will not appear in McCain commercials."
