In email to supporters, Vice President Joe Biden promises tonight to "tell the truth and stand up for what we believe in." The subject line of Biden's email reads, "My promise to you and Barack tonight."
"I told Barack I have one mission tonight: tell the truth and stand up for what we believe in," writes Vice President Biden. "Our side is always going to win when we do that."
Biden then portrays himself and President Barack Obama as underdogs. He writes, " But, Daniel, take a look at what we're up against this week:"
-- It's one of the last four weeks we have remaining.
-- This week alone, the other side is spending nearly $37 million on Mitt Romney's behalf in eight battleground states.
-- The resources we have in the bank at midnight tomorrow will determine how big we can go for our final push.
And then Biden asks for campaign cash. "It's urgent that everyone gets on board -- and fast. That means you, and that means now. Please don't wait any longer," he writes. "Donate $5 or more right now, before I head up on that debate stage."
I can't predict if Paul Ryan will follow Mitt Romney's lead tonight, hiding and flat-out denying their unpopular ideas, or if he'll come prepared to have a real debate about where this country should go.
Trust me, I'm ready for anything, but I can't do this alone. Nearly 4 million grassroots donors have stood up and said they'll be a part of what we're building together -- I'm hoping you'll take this opportunity to join them.
Your donation will put us in the strongest position possible tomorrow, ahead of a major budget-decisions deadline.
