Barack Obama actually said...

"The vice presidency is the most important decision that I will make before I'm president."

"Listen, there's no decision that I'm going to make that's going to be more important before the November election. I intend to do it right, and I'm not going to do it in the press."

"Choosing change."

"Choosing the right running mate has always been a high-stakes decision for presidential candidates, but this year may be the most important decision for these candidates in recent history."
