Or she's taking the opportunity to drive the last nail into the Clinton coffin.
I tend to think she realizes the value will drop, as Tallguy said, rather than wanting to shoot down the Clintons. Remember, this is the woman who told the Associated Press: “I can’t help but want to support my own gender, and [Hillary]’s as experienced as any of the others, except maybe Joe Biden.”
Note that she also described Biden as “smart, sexy, and experienced.” So it was a difficult decision for her, Hillary or Joe....despite the fact that she had earlier sued Hillary.
So...now I'm reconsidering. This woman is nuts enough to do anything!
