A
new poll in the Wisconsin Senate race finds openly lesbian U.S. Rep. Tammy Baldwin leading or tied with all but one of the four Republicans
competing in the GOP primary.
However, the candidate that Baldwin
trails, Tommy Thompson, is facing political attacks from conservative
groups. The former Wisconsin governor is well known in the state, which
political observers say is helping his poll numbers, but his popularity
could take a hit as the primary campaign heats up. Meanwhile, a group
funded by the the Koch brothers, who are conservative billionaires, has
launched a multimillion-dollar effort targeting Democratic Senate
candidates, including Baldwin.
