(CNN) - Artur Davis, a former Alabama congressman who switched voting Democrat to Republican, said he dropped his support for President Barack Obama out of frustration with what he described as the president's broken campaign promises.
Best known for seconding Obama's nomination at the Democratic National Convention in 2008, 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.

After three and a half years, however, Davis said the only change he has seen is a political party 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 former congressman announced at the end of May that he was switching to the GOP, leaving the door open to a future political bid as a Republican.
