New York: With big wins in Ohio and Pennsylvania, Hillary Clinton has continued to make the case for her continued run for the presidency. She also pointed to a flood of donations to her campaign post-Pennsylvania as a sign that people believe in her.

Clinton reportedly brought in her best one-day cash haul - $10 million (Dh36.75 million) - in the 24 hours after her victory on Tuesday night, write Jeff Zeleny and John M. Broder of The New York Times.

"While Obama had started April with more than $40 million, Clinton's campaign was essentially broke, with millions of dollars in debt. Her dire financial straits had threatened to derail her campaign before her nine-point victory in Pennsylvania allowed her to make a fresh case to voters and party leaders that she would be the strongest Democratic presidential nominee."

Right away, she's expected to pour much of that cash into Indiana, which votes May 6 and is also part of the economically depressed post-industrial belt that includes Ohio and Pennsylvania.

The Wall Street Journal writes that Clinton "has opened more than 20 offices across Indiana and has planned a tight schedule of events during the next two weeks for Senator Clinton, former President Bill Clinton and their daughter, Chelsea. Senator Evan Bayh, a former governor and Clinton backer, is spearheading Indiana efforts.

"We're going to be outspent, but we have enough money to get our message across," says campaign chairman Terry McAuliffe of the Indiana push.

How about race and electability? Adam Nagourney of The Times says it might be a greater issue than many Americans would want to acknowledge.

"While arguably critical to determining the viability of Obama's candidacy, the role of race is difficult to disentangle from the other strands of the political debate surrounding him, encompassing topics like values, elitism, ideology and experience.

Race issue

"Although some polling evidence hints at the depth of racial attitudes in this country and the obstacles Obama faces winning white voters, it has historically proved challenging to measure how racial attitudes factor into voter decisions. (Respondents do not tend to announce to pollsters that they will not vote for a candidate because he or she is black.)

Doug Wilder, the country's first elected black governor, told Bloomberg News that race won't disappear from people's minds, but added that he thought there were greater concerns to voters.

"Let's not kid ourselves again, the issue of race will not disappear; but I don't think it will predominate,, the former Virginia governor said in an interview at his office in Richmond, where he is now mayor. At the same time, he said, even if Obama is the nominee and heads into the fall with an apparent lead, the election "will be closer than any polls will suggest".
