Is it that she doesn't like one of the candidates? Is it that she's just trying to keep her name in the news? Whatever the reason, House Speaker Nancy Pelosi again said the chances of a presidential ticket featuring both Hillary Clinton and Barack Obama just ain't gonna happen, NBC's Mike Viqueira reported yesterday.

Whether the combination is Obama-Clinton or Clinton Obama, Pelosi said her "lifetime of political gut" told her some other arrangement will come to pass. "Take it from me, that won't be the ticket," she said. Earlier this week, Pelosi said essentially the same thing at a school in Boston, and at her press conference yesterday she was asked to clarify those remarks.

"I think it is impossible," Pelosi said, per a transcript of yesterday's presser released by her office. "However, let me just say I do think we will have a dream team. It just won't be those two names."

Pelosi said she is excited by the level of enthusiasm both candidates bring to the table, but that she hopes the nasty exchanges of recent days end soon. "I don't like to see disagreement among candidates, but when you set your cap to run for President, you make a decision to go," she said. "And sometimes in the enthusiasm of all the people you attract to the process, some of the exchange is not at the highest level. I think, by and large, it has been and will return to that level."

Asked specifically about Clinton backer Geraldine Ferraro's comments that Obama has an advantage for being black, Pelosi declined to take a shot at the former vice presidential candidate, instead offering subtle criticism. "I think that it's important that perceptions be understood by campaigns and whether -- whatever was the intention or whatever the good thoughts that people may have had about their statements, we have to remember how they are perceived by others," Pelosi said. "And I think that the Clinton campaign moving to, shall we say, put some distance was very important."

Neither Pelosi nor Senate Majority Leader Harry Reid have endorsed a candidate on their own, though those close to both top Democrats have made their own endorsements. Several key Pelosi allies in the House, most notably California Democrat George Miller, have backed Obama, while Reid's son Rory, the chairman of the Clark County Commission, was instrumental in delivering his state for Clinton.

As chair of the Democratic National Convention, Pelosi has said she will remain neutral in order to resolve any disputes that arise. But mentioning the unlikeliness of an Obama-Clinton ticket seems strange, and to go back to it twice only makes more ears perk up.
