PPP looked at match ups involving 5 Republicans (Paul Broun, Phil Gingrey, Karen Handel, Jack Kingston and Tom Price) and 3 Democrats (John Barrow, Jason Carter, and Max Cleland). Cleland is the only person in the whole bunch who has more than 50% statewide name recognition, with 48% of voters rating him favorably to 29% with an unfavorable view.
If Cleland could be coaxed into the race he would start out with a lead over every Republican we tested him against. He's up 1 against Price, 3 against Kingston, 5 against Gingrey, and 7 against Broun and Handel. Democratic prospects for winning the seat might not hinge on what could be an unlikely Cleland candidacy though. John Barrow trails by an average of only 4/10ths of a point against the Republicans we tested- leading Gingrey and Handel by 1, tying Broun, trailing Price by 1, and trailing Kingston by 3. Carter trails the quintet of Republicans we tested by an average of 3.8 points- he's down 2 to Broun and Gingrey, 4 to Handel, 5 to Price, and 6 to Kingston.
