Will Sen. Joe Biden be dropped from the Democratic Party ticket before Election Day?

Television pundits, talk radio personalities and blogs have been buzzing with speculation about a last-minute VP switch for the party.

On Fox's "Hannity & Colmes" last night, Sean Hannity asked Gov. Ed Rendell, D-Pa., "Will they replace Biden with Hillary ?"

...after today’s Obama-Biden speeches to a massive crowd in Springfield, Ill., many reporters are rolling back the tape and asking each other, “Did he really say that?”

When introducing his running mate, Obama said, “So let me introduce to you the next president - the next vice president of the US of America, Joe Biden.”

And then when it was Biden’s turn to speak, the Delaware senator called the presumptive Democratic nominee “Barack America” instead of Barack Obama.

“My friends, I don’t have to tell you, this election year the choice is clear. One man stands ready to deliver change we desperately need. A man I’m proud to call my friend. A man who will be the next president of the United States, Barack America,” Biden said, per ABC News’ Sunlen Miller.
