Biden, Dodd drop out

After posting just 1 percent support in Iowa, Sen. Joe Biden, D-Del., and Sen. Chris Dodd, D-Conn., are dropping out of the race.

Here's an e-mail Biden sent to supporters:

I wanted to send a short note to say how incredibly grateful I am for the support you have shown me in this campaign. My entire family and I are in awe of the many of you who opened up your hearts and homes to us during the campaign to give us a chance to change this race, and the country, for the better.

And we succeeded. Whether it was keeping the Democratic Party focused on finding a political solution in Iraq, securing funding for MRAP vehicles for our troops, or calling for a fundamentally new approach to Pakistan, we had an impact on this election in ways that will reverberate into next November, when we elect a Democrat to the White House.

Although I am ending my Presidential campaign, I am not going away. I'm returning to the Senate as the Chairman of the Senate Foreign Relations Committee and will continue to ensure that we protect the nation's security and show our country that Democrats know how to keep America safe, keep our commitment to our troops and restore our country's respect in the world.

Again, thank you so much for making all of this possible.

Joe
