Obama extends streak with Wis., Hawaii wins

Obama began the evening with eight straight primary and caucus victories, a remarkable run that has propelled him past Clinton in the overall delegate race and enabled him to chip away at her advantage among elected officials within the party who will have convention votes as superdelegates.

The economy and trade were key issues in the race, and seven in 10 voters said international trade has resulted in lost jobs in Wisconsin. Fewer than one in five said trade has created more jobs than it has lost.

The Democrats' focus on trade was certain to intensify, with primaries in Ohio in two weeks and in Pennsylvania on April 22.

Obama's campaign has already distributed mass mailings critical of Clinton on the issue in Ohio. "Bad trade deals like NAFTA hit Ohio harder than most states. Only Barack Obama consistently opposed NAFTA," it said.

Clinton's aides initially signaled she would virtually concede Wisconsin, and the former first lady spent less time in the state than Obama.

Even so, she ran a television ad that accused her rival of ducking a debate in the state and added that she had the only health care plan that would cover all Americans and the only economic plan to stop home foreclosures. "Maybe he'd prefer to give speeches than have to answer questions" the commercial said.

Obama countered with an ad of his own, saying his health care plan would cover more people.

McCain sees finish line
Unlike the Democratic race, McCain was assured of the Republican nomination and concentrated on turning his primary campaign into a general election candidacy.

In one sign of progress in unifying the party, he split the conservative vote with Huckabee in Wisconsin.

Huckabee parried occasional suggestions - none of them by McCain - that he quit the race. In a move that was unorthodox if not unprecedented for a presidential contender, he left the country in recent days to make a paid speech in the Grand Cayman Islands.

McCain picked up endorsements in the days before the primary from former President George H.W. Bush and former Massachusetts Gov. Mitt Romney, a campaign dropout who urged his 280 delegates to swing behind the party's nominee-to-be.
