The open Wisconsin Senate race has been close ever since incumbent Herb Kohl (D) announced that he would not seek re-election. Now, Rasmussen Reports just released a new survey (May 9; 500 likely Wisconsin voters) showing former four-term governor Tommy Thompson to be holding a substantial advantage for the first time over Madison Rep. Tammy Baldwin (D-WI-2). According to the RR data, Thompson would lead the general election 50-38 percent if he and the congresswoman win their respective party nominations. Baldwin is the consensus Democratic candidate while Thompson faces three potentially strong Republican opponents. Virtually every other poll has shown the race to be within very small margins.
Pitting Baldwin against the other Republicans, Rasmussen also finds very close spreads. Against former Rep. Mark Neumann (R-WI-1), Baldwin trails 42-45 percent. Opposing state Assembly Speaker Jeff Fitzgerald (R), the congresswoman leads 45-41 percent.
The Wisconsin race, along with four others, could very well decide which party will control the Senate majority in the next Congress.
