Three Georgia Democrats are facing primary challenges Tuesday — one for voting against healthcare reform and another who questioned whether Guam could tip over.

Rep. John Barrow (D-Ga.) infuriated his fellow Democrats on Capitol Hill by voting against the healthcare legislation in March. Only 10 members gave to his campaign in 2010, down from 22 in the 2008 cycle. 

Former state Sen. Regina Thomas (D) hoped to capitalize on Barrow’s controversial vote and her demographic advantage in the primary for the heavily African-American district. But she failed to raise enough money to be competitive. Morever, this is her second crack at Barrow, having lost to him by more than 50 points in 2008. Democratic strategists expect Barrow to survive Tuesday’s vote.  

Meanwhile, Rep. Hank Johnson (D-Ga.) — who questioned whether Guam could “tip over and capsize” — is up against former DeKalb County chief Vernon Jones and DeKalb County Commissioner Connie Stokes. 

Johnson has the backing of President Obama and has raised and spent significantly more than his opponents. He even released a catchy campaign song, although it was later taken down from his website for unknown reasons.  

Rep. David Scott (D-Ga.) also faces a primary challenge from Democrats Mike Murphy and Michael Frisbee, but he too is expected to retain the nomination.
