Washington insiders are now betting on Joe Biden as Obama's Veep pick and the announcement could come very soon - even as you're reading this.
Will it be Biden?
Well, Obama does need gravitas and Biden seems to have it.
Lately, Obama's youth and inexperience have been on ample display. And the Saddleback Church forum and Georgia crisis have only exacerbated the situation.
On the surface Biden would seem like a safe pick but watch out: Biden can be a loose cannon. After all, he is the guy who said of Obama: "I mean, you got the first mainstream African-American who is articulate and bright and clean and a nice-looking guy. I mean, that's a storybook, man."
Bright? Clean? Nice-Looking? Biden later apologized. Still, his comments took second place on Time magazine's list of Top Ten Political Gaffes of 2007.
And Biden also said Obama had a "Johnny come lately" position on Afghanistan by asking for more brigades last summer.
Plus this: Biden's own 1988 presidential campaign came to an abrubt end when he was caught plagiarizing a speech by Neil Kinnock, then-leader of the British Labour Party.
