Senator Hillary Clinton may be warming up to the idea of teaming up with her presidential rival Senator Barack Obama. But Obama said Monday he is not interested in running for vice president. Obama says if Bill and Hillary Clinton are actually dreaming about a Clinton-Obama ticket with her as the presidential candidate and him as the VP, then they need a wake-up call and a reality check because he is the frontrunner, not her. And after getting back on the winning track in Wyoming on Saturday, Obama is expected to make it two in a row in Mississippi Tuesday before the race moves on to Pennsylvania in late April. "As I understand it, both senator clinton and president clinton repeatedly talked about how I would be a great vice president," said Obama. Obama had some fun Monday on the campaign trail in Mississippi, where he's favored to win the primary easily, by ridiculing the Clintons for suggesting he'd make a good vice-presidential candidate for Hillary Clinton when Obama has already won 11 more states than her, picked up 111 additional delegates and racked up more votes. "I don't know how somebody who is in second place is offering the vice presidency to the first who is in first place. I want everybody to be absolutely clear; I'm not running for vice president. I'm running for president of the United States of America," said Obama. But while Obama is having fun in Mississippi, the Democratic Party is dealing with a much more serious issue of how to apportion delegates or reschedule elections in Michigan and Florida, where the earlier primaries won by Clinton were actually meaningless because the states were stripped of their delegates for ignoring the party's order to not hold contests in January. "I think the chairman of the DNC knows he has to have a program in place that allows in some way Michigan and Florida to be fully participant at the convention," said Rep. Rahm Emanuel, (D) Chicago. "We probably have to move to a revote, whether it's by mail or primary," said Al From, Democratic Leadership Council. "I think the Democratic Party should pay for it. I don't think the taxpayers of Michigan or Florida should have to pay for it. It's a lot of money," said Chicago Mayor Richard Daley. The cost of re-voting in Florida and Michigan could be as high as $30 million if they do the primaries all over again, and that's why there's been a lot of talk about the possibility of voting by mail, which is a lot less expensive. And at the end of the day, the cost will probably be divided up between the democratic parties in Michigan and Florida and the Democratic National Committee and the campaigns themselves, not taxpayers, although two prominent governors in Pennsylvania and New Jersey are now talking about raising $15 million themselves from wealthy donors. Two things are clear, they will re-vote in those two states in some fashion, and Obama will not be a vice presidential candidate. It sounds like all or nothing for him.
