From earlier today:

At a news conference at the Train Depot in Hattiesburg, Miss., where she held a rally to finish a two-day trip to Mississippi, where she is not expected to fare well in Tuesday's primary, Sen. Hillary Clinton said Obama's campaign did the right thing by separating itself from Samantha Power, Obama's former foreign-policy aide, who called Clinton a "monster" in an interview.

But Clinton said Power raised more troubling issues than name-calling in an earlier interview with the BBC which she said raises questions about whether the Illinois senator is once again telling voters one thing while aides tell people outside the country something else.

"I want to say a few words to start about something that one of Sen. Obama's top foreign policy aides told the BBC recently about Iraq. Sen. Obama has made his speech opposing Iraq in 2002 and the war in Iraq is the core of his campaign, which makes these comments especially troubling. While Sen. Obama campaigns on his plan to end the war, his top advisors tell people abroad that he will not rely on his own plan, should he become president.

"This is the latest example of promising the American people one thing on the campaign trail and telling people in other countries another. We saw this with NAFTA as well. He''s attacked me continuously for having no hard exit date and now we learned that he doesn't have one. In fact, he doesn't have a plan at all, according to his top foreign-policy advisor. If he keeps telling people one thing while his campaign tells people abroad something else, I'm not sure what the American people should believe.”

This issue with Samantha Power is the kind of thing candidates have nightmares about: A high-ranking aide is caught slandering the opposition; the opposition calls for the aide's resignation; aide resigns; opposition then pounces anyway. In other words, a no-win for Obama. For the campaign, a Wyoming victory can't come fast enough.
