Barack Obama has pulled almost even with Hillary Clinton in endorsements from top elected officials and has cut into her lead among the other superdelegates she's relying on to win the Democratic presidential nomination. Among the 313 of 796 superdelegates who are members of Congress or governors, Clinton has commitments from 103 and Obama is backed by 96, according to lists supplied by the campaigns. Fifty-three of Obama's endorsements have come since he won the Jan. 3 Iowa caucuses, compared with 12 who have aligned with Clinton since then.
