Although Secretary of State Hillary Clinton has said that she has no intention in running for president again, President Barack Obama's former campaign manager wouldn't rule it out Sunday.

David Plouffe told NBC's David Gregory that he doesn't anticipate an Democratic challenger but deflected questions about a possible Clinton run.

"Do you envision a primary challenge from another Democrat in 2012 against this president?" asked Gregory.

"I can't imagine that," replied Plouffe.

"Can you rule out based on actual information that Secretary of State Clinton would not pursue the presidency again and would not challenge President Obama?" Gregory wondered.

"You saw this week they're working so well together. Working on Middle East peace and it's a wonderful partnership. I think that was a really inspired choice by the president and Secretary of State Clinton is doing a remarkable job," said Plouffe.

"Is that yes, no or maybe?" pressed Gregory.

"They're a team and a great team for America," Plouffe answered.

In a 2009 NBC interview, Clinton said "no" three times when asked if she would run for president again.

(Nicole:) Gregory puts Plouffe in the impossible position of having to "prove" a negative. Nice.

The media just can't get enough of these "Hillary Clinton Backstabber" narratives. It doesn't matter how many times Clinton denies it, it doesn't matter how much support Obama gives her in her position of Secretary of State, the media loves this insinuation that Clinton is just itching to undermine Obama and grab all the power herself. It's sick and sexist against Clinton and it further pushes the "Obama is an ineffectual wimp" meme as well that the Republicans love so much.
