A new Marquette University Law School poll shows a surprising turnaround in the race for Wisconsin's open senate seat.

Likely voters now favor Representative Tammy Baldwin 50 to 41 over former governor Tommy Thompson. It's a major change from last month's poll that had Thompson leading by the same margin.

Thompson made a stop at L.B. White in Onalaska Wednesday.

The former governor says he doesn't put much stock in this latest poll. He says the amount of volunteers and money he has coming in is an indication that his campaign is strong.

He points out that not long ago polls had him up by double digits.

He says his opponent Tammy Baldwin has been on TV attacking him for four weeks, but he hasn't had the resources to attack back.

"We had a very spirited primary and we of course used all of our resources in the primary so we had to take a hiatus, we had to go out and raise new dollars and now we're up on television and you will see the changes be reflected in the next polls," said Thompson.

Thompson says he's being outspent five to one in this race, but still feels he can be competitive.
