Rep. John Barrow (D-Ga.) is facing a difficult primary challenge because of his vote against the healthcare reform bill but that doesn't mean he's switching parties.

On Tuesday Barrow tried to quash rumors he planned to walk across the aisle to join the GOP.

"I am not switching parties, nor have I ever given any indication that I would. There is no truth to this rumor," Barrow told the Atlanta Journal-Constitution.

The Savannah Democrat faces a primary rematch with state Sen. Regina Thomas (D), who's getting support from on account of Barrow's "no" vote.

The conservative-leaning American Spectator had reported that as a result of Thomas getting the liberal group's backing "some Georgia Republicans now believe that the Democrat may be contemplating a switch to the GOP."
