Former Senate majority leader Thomas A. Daschle (S.D.), a co-chair of the Obama campaign, said Sen. Barack Obama does not have “any interest in being vice president,” because “he’s going to be our presidential nominee.”

Obama, sticking to his vow to be tougher on Sen. Hillary Clinton, sent out a memo sharply criticizing Clinton’s dirty tactics and accusing her campaign of attempting “to deceive the American people just so that they can win this election.”

In the memo titled “Doing Whatever It Takes to Win,” Clinton was accused of “tearing Barack Obama down” and said her campaign “should stop telling the American people things that they know aren’t true.”

Obama, who is leading Clinton by 140 pledged delegates, easily won the Wyoming caucus and is leading in the polls going into Mississippi’s primary tomorrow. He is expected to win most of the remaining caucuses and primaries except maybe Philadelphia where Clinton has a slight edge.

But Clinton may still pull a rabbit out of her hat if the superdelegates go against the will of the people and give her the nomination. Al Sharpton and others are ready to protest if that happens.

Daschle said it would be a “travesty” if Obama maintains his lead among pledged delegates but an advantage among superdelegates allows Clinton to win the nomination.

“I don’t see how we could possibly do anything other than respect the will of the people who have voted in caucus and primary states all over the country,” he said on NBC’s “Meet the Press.” “And what it would say to the world, to the country, that we’d overturn the verdict of those… elections would be a travesty for… the party and for the country.”
