U.S. Rep. John Barrow, from GA’s 12th congressional district, is a vanishing breed: the lone remaining white Democratic congressman from the deep south, according to Politico.

He has walked a tightrope for several years now – still a Democrat, but a conservative one on many issues, with an independent streak. It worked for him in 2010 when he was last reelected. But that was before redistricting. He now sits in a district tailor-made to elect a Republican.

Can he survive again? If so, he should probably go on the CBS reality program “Survivor.” Or at least write books and hold seminars on winning elections when you are not supposed to.

Barrow has voted with Republicans on some key business and tax bills since he has been in the House. This year he was even endorsed by the U.S. Chamber of Commerce, who is advertising on his behalf. He also voted against President Obama’s Affordable Health Care Act, one of the few Democrats to do so, earning the wrath of many in his own party.

Barrow’s latest gambit is his refusal to attend the Democratic National Convention in Charlotte. So he has laid down the gauntlet: he is against the President’s signature piece of legislation and he will not attend his re-coronation party in September.

I don’t know if Rep. Barrow’s independent, tough guy, go-it-alone strategy will work. But you have to give him credit for trying.
