Hillary is no longer any use for Obama. Obama is a huge negative for a Hillary run for President. To be credible she has to destroy Obama politically.
The game is afoot.
And it won't do the old hag a bit of good. She's well past her expiration date on the national stage, and is more boring than yesterday's regurgitated news.
Think about it. Hillary has been a part of national politics for 22 years now. That's older than a lot of Obama voters. Obama beat Hillary, in part, because he was perceived as young and fresh. Hillary was perceived as old and stale.
This perception will only be magnified next year, when she's 69, and STILL a stale has-been who should have gotten the hook a decade ago.
