"The president says, 'I don't care.' He's not accountable anymore," Hagel says, measuring his words by the syllable and his syllables almost by the letter. "He's not accountable anymore, which isn't totally true. You can impeach him, and before this is over, you might see calls for his impeachment. I don't know. It depends how this goes."
This is true. Just like former Rep. Bob Barr wanted to impeach Clinton from the moment Clinton took office and former Rep. Cynthia McKinney wanted to impeach Bush right after 911. You'll have these fringe elements making noise, but I doubt it gets much farther than that. It would be political suicide for the Democrat nominee.
