Obama flip-flopped on financing

WASHINGTON — The campaign of Democratic presidential hopeful Sen. Hillary Rodham Clinton hammered rival Sen. Barack Obama on Sunday for refusing to reaffirm his commitment to accept public financing in the general election, a development a top aide criticized as "a pretty big flip-flop" and an opening for Republican attack.

Clinton hasn't acknowledged that Obama is likely to be the Democratic nominee — she says she is — and she also hasn't promised to accept public financing herself. The issue, Clinton spokesman Howard Wolfson says, is that Obama made a campaign pledge but now won't promise to keep it.
