Artur Davis

In 2008, he was one of the biggest champions for Barack Obama, even serving as an Obama campaign co-chairman and seconding Obama’s nomination at the Democratic National Convention.

But that was then and this is now.

Today, Artur Davis, a former four-term Democratic congressman from Alabama is now supporting Republican Mitt Romney for president, and is joining him on the campaign trail in Arlington, Va.

Just last month in Falls Church, Va., Davis gave a rousing address to the Northern Virginia Tea Party, rallying the crowd to defeat his former ally Obama.

The Birmingham News indicated “Davis’ sermon-like speech, invoking both the 1980 Reagan revolution and Rosa Parks, earned a standing ovation and chants of ‘USA.'”

During that speech (scroll down for video), Davis also encouraged young people: “You tell everybody your age that being Republican is cool, being conservative is the right thing to do. It’s the right set of values. You testify, you minister, and you bring ’em on board with you, because we’re not going to concede young people to the Democratic Party in 2012.”

Two years ago, Davis ran unsuccessfully for governor of Alabama, and in May of this year, he left the Democratic Party to become a Republican.

In June, Davis said he thinks his former political party was becoming more unwelcoming toward 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,” he said on CNN’s “The Situation Room with Wolf Blitzer.” “Obviously the election will determine that.”

According to the Hill, Davis was the only black Democrat in the U.S. House of Representatives to vote against Obamacare.

The Hill notes, “He has grown increasingly vocal over his disagreements with his party, at one point lamenting on his website that ‘[the Democratic Party of today] is not Bill Clinton’s Democratic Party.'”

ABC News called Davis “this season’s most high-profile political turncoat, which puts him in some heavy-hitting company.”
