Really?
The only way Clinton's not supporting Obama is if she pulls a win off.
She's already said publicly multiple times that she will. She's changed her tone and become far less negative.

She cannot make it as an independent candidate and she knows it. So she's going to do what's best for her future and stick by her party's nominee.
She'd be insane not to.
