HANOVER, N.H. (AP) — Presidential challenger Mitt Romney accused President Barack Obama of failing to lead in a time of economic peril but sounded less conservative than his Republican rivals in their debate Tuesday night, defending the 2008-2009 Wall Street bailout and declaring he could work with "good" Democrats.

Romney also gave one of his most spirited defenses of his health care initiative when he was Massachusetts governor, legislation that Obama has called a partial blueprint for his own national overhaul. By positioning himself closer to the political center on several points, Romney sought to underscore his claim that he can draw crucial independent voters in next year's general election.

His chief rival, Texas Gov. Rick Perry, seemed less sure-footed. He repeated his main talking points about free enterprise but did little to dent Romney.
