Obama Misspeaks, Calls Biden 'The Next President'; Biden Calls Obama 'Barack America'

(ABC News) - Journalists who were awake until the wee hours waiting for confirmation that Sen. Joe Biden, D-Del., was indeed Barack Obama's running mate, cannot be blamed if their hearing is a little fuzzy today.

But 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.
