Obama and Clinton face off in Wisconsin, Hawaii as Democratic contest veers negative

WASHINGTON (AP) " Barack Obama and Hillary Rodham Clinton squared off in a scrappy Wisconsin primary and in laid-back Hawaii caucuses Tuesday, their struggle for the Democratic presidential nomination veering toward the negative.

Wisconsin offered 74 national convention delegates, and an early test of support in industrial states such as Ohio and Pennsylvania.

There were 20 delegates at stake in Hawaii, where neither Clinton nor Obama campaigned in person.

Obama began the night with 1,281 delegates in The Associated Press count, and Clinton with 1,218. It takes 2,025 to win the nomination at the party's national convention in Denver.

Independents cast about one-quarter of the ballots in the Wisconsin race between Obama and Clinton, and roughly 15 percent of the electorate were first-time voters, according to preliminary results from interviews at polling places. Obama has run well among independents in earlier primaries.

The economy, and trade in particular, was a key issue, according to the survey.

Seven in 10 Democratic primary voters said U.S. trade with other countries winds up costing jobs in Wisconsin. Fewer than one in five said it creates more jobs than it loses.

Republican front-runner John McCain hoped to inch closer to wrapping up the GOP nomination in primaries in Wisconsin and Washington, with 56 delegates at stake.

The Arizona senator had 908 delegates, and his closest remaining rival, former Arkansas Gov. Mike Huckabee, had 245. Texas Rep. Ron Paul had 14.

Obama began the evening with eight straight primary and caucus victories, a 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.

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 covers 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.

In San Antonio on Tuesday, Obama said her idea to freeze the monthly rate on adjustable rate mortgages for at least five years would raise rates on new mortgages. "Even more families could face foreclosure," he said. "That's why one economic analyst called her plan disastrous."

The campaign grew increasingly testy over the weekend, when Clinton's aides accused Obama of plagiarism for delivering a speech that included words that had first been uttered by Deval Patrick, the Massachusetts governor and a friend of Obama.

"I really don't think this is too big of a deal," Obama said, eager to lay the issue to rest quickly. He said Clinton had used his slogans, too.

Even before the votes were tallied in one state, the campaigners were looking ahead.

Texas and Ohio hold primaries on March 4, and some of Clinton's backers have said the one-time front-runner cannot afford to lose either.

Already, she and Obama have begun advertising in Texas, with 193 delegates, and Ohio, with 141, and both visited the two states in the days before Wisconsin primary.

The Pennsylvania primary, with 158 delegates, is April 22, the last big state to vote.

In deference to Wisconsin, McCain began his day in Brookfield, a Milwaukee suburb, but planned to watch the returns in Columbus, Ohio.

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

At the Wisconsin rally, McCain's wife, Cindy, said, "I'm proud of my country, I don't know about you, if you heard those words earlier. I'm very proud of my country."

She appeared to be making a reference to Michelle Obama's comment on Monday in Milwaukee: "Let me tell you, for the first time in my adult life, I am proud of my country."

Asked by reporters if Mrs. McCain was referring to the remark by the Illinois Democrat's wife, McCain said: "I don't think we have any comment on that."

Mrs. McCain added, "I just wanted to make the statement that I have, and always will be, proud of my country."

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 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.
