GOP Senate candidates differ on who best to take on Baldwin

The four Republican U.S. Senate candidates have some differences over  what it takes to defeat likely Democratic nominee Tammy Baldwin.

Polls indicate that former Wisconsin Gov. Tommy Thompson is leading the GOP Senate primary. Thompson suggests that defeating President Obama might be difficult in Wisconsin this fall, and Thompson would  help the GOP presidential ticket, "We haven't carried the state of Wisconsin as a Republican since Ronald Reagan's second term. You're gonna have to have somebody able to bring the votes back to the Republican side and I've carried the state of Wisconsin five times."

Former Wisconsin Congressman, and now homebuilder Mark Neumann says he has the conservative backing needed to defeat Baldwin.

Businessman Eric Hovde says he has the private sector background that would win in November.

Hovde also says he can win more younger voters and female voters, though he didn't explain that remark other than to say he would work hard to get that backing.

State Assembly Speaker Jeff Fitzgerald says while being an ally of Gov. Scott Walker, Fitzgerald has shown guts, "You know what people are starved for? They're starved for political courage. That's what I bring to the table. I've been battle-tested for past 15 months of fighting for you."

Tammy Baldwin's campaign says she would take on special interests and stand up for the middle class and small businesses, while the Republican candidates would put millionaires and large corporations ahead of the people of Wisconsin.
