The Wisconsin Senate race looks like a tossup if former Gov. Tommy Thompson (R) gets in.
A new Public Policy Polling (D) survey shows Sen. Russ Feingold (D-Wis.) leading Thompson 47-44 in a hypothetical matchup. Other recent polls have shown a lead for Thompson. PPP has shown some movement toward Thompson, after Feingold led 50-41 in November.
Thompson does have a slightly worse personal numbes, with a 40 percent favorable rating and 44 percent unfavorable. Feingold's approval remains positive but under 50 percent, at 45 percent approval and 41 percent disapproval.
Recent projections have put the possibility of Thompson running at 50-50 or better.
