It smells like.......desperation.
And to the people out there that say "We can beat Hillary, but Obama? Not so much...". ...Remember that a Hillary! presidency was more or less a foregone conclusion this time last year.
I say that it's better to knock her out early, drive a stake through her heart, and liberally salt her burial plot. If she gets the (D) nomination, all it would take is a viable 3rd party to split the (R) ticket..and she'd be in the White House. Heck, in 2000, Guilani would have stomped her in the Senate race but he got floored by prostate cancer, leaving us in the situation that we're in now.
Anything can happen in an election. Better than she doesn't have a chance to start with.
