A few hours before he debated Rep. Paul Ryan Thursday night, Vice President Joe Biden (or a 22-year-old campaign staffer in Chicago) sent the following message to supporters:
"I told Barack I have one mission tonight: tell the truth and stand up for what we believe in. Our side is always going to win when we do that."
Biden's team needed a win. Mitt Romney emerged from last week's debate with more momentum than he's had in nearly two years of campaigning. So, what do you think, who won Thursday night's showdown, Biden or Ryan?
