Obama 2008 Co-Chair Hits Trail ... for Mitt

The man who seconded Barack Obama's presidential nomination at the DNC in 2008 is now campaigning against the president. Artur Davis was co-chair of Obama's first campaign, but he'll today campaign in Virginia in support of Mitt Romney, a Romney campaign aide tells CNN. Davis served four terms as a Democratic congressman, but announced a switch to the Republican Party in May.

"I think the Obama administration has candidly gone too far to the left. You can raise all kinds of questions on whether that's good politics or not," Davis told Wolf Blitzer. "Obviously the election will determine that." Davis will appear at an Arlington event today, where he will "discuss Mitt Romney and Paul Ryan’s bold ideas to strengthen the middle class and deal with our long-term debt," a Romney insider tells Buzzfeed.
