Barack Obama was spending the day at home in Chicago on Wednesday after his double-digit win in North Carolina's primary.

Hillary Rodham Clinton will be back on the campaign trail after a two-point victory in Indiana.

Clinton has a noontime appearance Wednesday in West Virginia, the site of a primary next Tuesday.

On Thursday, she will campaign in West Virginia, South Dakota and Oregon.

Overnight, Obama sent an e-mail, telling potential donors: "We have a clear path to victory." He's now less than 200 delegates shy of the number needed to secure the Democratic nomination.

Clinton also made a fundraising pitch, telling cheering supporters in Indianapolis last night: "I need your help to continue our journey."

She vowed to compete tenaciously for West Virginia next week and Kentucky and Oregon after that, and to press "full speed on to the White House."

Obama's campaign is dropping broad hints that it's time for the 270 remaining unaligned party figures known as superdelegates to get off the fence and settle the nomination.

The Democratic rivals will square off in West Virginia on May 13. A Rasmussen poll taken Monday has Clinton leading 56 to 27 percent over Obama, with 17 percent undecided. West Virginia has 39 delegates up for grabs and should be favorable ground for Clinton because of her success appealing to blue-collar voters, who are prevalent in the state.

Kentucky and Oregon follow on May 20 with their 60 and 65 delegate votes at stake, respectively.

Kentucky posted almost identical results to West Virginia in a recent poll, with Clinton leading 56 to 31 percent over Obama, with 13 percent undecided, according to Rasmussen. A poll taken on Monday in Oregon has Obama leading the New York senator 51 to 39 percent, with 10 percent undecided.

It is likely not enough delegates will be at stake in the remaining primaries through June 3 to give either Obama or Clinton the 2,025 delegates necessary to win the nomination.

Obama said Tuesday he knows the marathon struggle for the Democratic nomination has caused "bruised feelings on both sides," but he predicted the party will unite by November.

Speaking at a victory party in Raleigh, N.C., on Tuesday night, Obama also sought to answer charges that he was having trouble winning in big states that will be important in the general election.

He characterized the North Carolina win as "a victory in a big state, a swing state."

North Carolina is the nation's 10th largest state in population.

Obama told supporters he won by overcoming "politics of division and the politics of distraction." He said Americans "aren't looking for more spin; they're looking for honest answers."

Clinton eked out a narrow victory over Obama in Indiana, with the tallies from 99 percent of the Indiana precincts showing Clinton with 51 percent to Obama's 49 percent.

That margin is a little more than 22,000 votes of the more than 1.2 million cast.

The outcome wasn't clear for more than six hours after the polls closed.

The uncertainty stemmed from slow counting in Lake County near Obama's home city of Chicago.

Before the race was called for her, Clinton declared victory and told supporters "it's full speed on to the White House."

Race Plays Key Role

On Tuesday, race again played a pivotal role, as whites in Indiana and North Carolina leaned solidly toward Clinton and blacks voted overwhelmingly for Obama, exit polls showed. Half the voters said they were influenced by the focus on Obama's former pastor, the Rev. Jeremiah Wright.

According to preliminary results from the exit polls, two-thirds of whites in both states who have not completed college were supporting Clinton, which the New York senator could use to fortify her argument that she would be the stronger Democratic candidate in the November general election. Of 28 states that have held primaries in which she and Obama competed before Tuesday, Clinton had prevailed with working-class white voters in 25.

Wright was a looming factor in the voting, with half in each state saying he was important in choosing a candidate. Of that group, seven in 10 in Indiana and six in 10 in North Carolina backed Clinton. Those discounting him as a factor heavily favored Obama. In North Carolina, Obama got more votes from people saying they discounted the Wright episode than Clinton got from those affected by it.
