Another juicy tidbit from Game Change via Jonathan Martin of Politico:

Of all the freshly revealed anecdotes, though, none may be as eye-opening as the previously-unknown friction between the president and vice-president - which on Saturday a Biden spokesman dismissed as "rumors." The tensions began in September of 2008 word got back to Obama's campaign headquarters that Biden had told reporters on his campaign plane that he was more qualified than his running mate to be president.

"A chill set in between Chicago and the Biden plane," Halperin and Heilemann write in the book, to be released Monday. "Joe and Obama barely spoke by phone, rarely campaigned together."

[...]

But when Biden, at an October fund-raiser in Seattle, famously predicted that Obama would be tested with an international crisis, the then-Illinois senator had had enough.

"How many times is Biden gonna say something stupid?" he demanded of his advisers on a conference call, a moment at which most people on the call said the candidate was as angry as they had ever heard him.

For his part, the authors write, Biden wasn't pleased with the campaign's direction.

After a prep session for a "Meet the Press" appearance following the Democratic convention, Biden was incredulous when he was briefed by campaign aides about the ticket's tax policy. He told them: "Well, it's your campaign. I'll say what you want me to say. But after Election Day, all bets are off."

Following his campaign plane braggadocio about being more qualified than the man who put him on the ticket, Biden's access to the press was limited and he grilled new staffers that were assigned to him to try and determine if they were part of his team or loyal to Chicago.

Biden's access to the press is still limited. But that hasn't stopped the human gaffe machine from delivering a jaw dropper every once and a while.

Will Obama keep Biden as Veep in 2012? Now that this information is out, I don't see how he can.
