With two weeks to go until Election Day, Wisconsin’s U.S. Senate candidates were on the campaign trail Monday to kick off early voting in the state. They each spent the time criticizing their opponent.

Republican Tommy Thompson made two stops in Green Bay, one as part of a National Federation of Independent Business’ bus tour. The former governor says if elected to the U.S. Senate, he’ll create policies that benefit business owners, like lower taxes and fewer regulations. He criticized Democratic opponent Tammy Baldwin as being too liberal to represent Wisconsin in the Senate, “My opponent, ladies and gentlemen, is the most radical, liberal member of the House of Representatives. Not by my estimation, by her own words, her deeds, her vote of her members and also what the National Journal has said.”

Baldwin campaigned in La Crosse at the county’s Democratic Party headquarters. The Congresswoman says she’s trying to avoid hearing the attacks, especially on TV commercials, “When you stand up to Wall Street, as I have, when you stand up to the big health insurance companies, big pharmaceutical companies, they’re going to start name calling, but I think the voters understand that and they’re looking for somebody that’s going to be fighting squarely on their side, not the powerful interests who are funding those ads.”

Baldwin told supporters that she’s fighting for the middle class and that Thompson is working on behalf of Washington lobbyists.

Both U.S. Senate candidates are encouraging early voting, which began Monday in Wisconsin. Residents can vote in-person at their municipal clerk’s office until November 2.
