(CNN) - A former four-term Democratic congressman from Alabama and one time strong supporter of President Barack Obama will campaign for Mitt Romney Wednesday.
A Romney campaign aide confirms to CNN that Artur Davis will stump for the presumptive Republican presidential nominee in the battleground state of Virginia.
Artur Davis appears Wednesday on CNN's "The Situation Room with Wolf Blitzer." Watch the program from 4 p.m. ET – 7 p.m. ET.
Davis, who is black, may be best known for seconding Obama's nomination at the Democratic National Convention in 2008, when he served as an Obama campaign co-chairman. Davis said he had hoped Obama's presidency would make a huge dent in race relations, as well as move the Democratic Party further to the center.
In 2010, Davis made an unsuccessful bid for governor of Alabama. In May he announced he was switching to the GOP, leaving the door open to a future political bid as a Republican.
Davis said in June that he thinks his one time political party was becoming more unwelcoming towards Southern conservative Democrats.
"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 said on CNN's "The Situation Room with Wolf Blitzer." "Obviously the election will determine that."
The Romney campaign says Davis will team up with Virginia GOP Victory Chairman Pete Snyder and a local business owner at an event in Arlington.
