Easy: Former Clinton White House whore, with a VERY big mouth. She then was shoved off on the DNC when her Master left office, until she made the unbelievably imbecilic choice to join up with Edwards.
She considers herself to be a very funny person, and takes great delight in things like issuing press releases that are nothing but Letterman-style Top Ten lists making fun of George W. Bush. And of course, they - like all her "comedy" bits - are deeply unfunny. Cringeworthy, in fact. And I'm not just saying that because she always uses her "talents" to attack Republicans. She's not funny, period.
