Obama brushes aside the notion that his rhetoric is insubstantial. He says he would inspire people to come together to solve problems.

"The most important thing we can do right now is re-engage the American people in the process of governance, to get them excited and interested again in what works and what can work in our government."

On the Republican side, Arizona Senator John McCain has a clear lead nationwide and no one expects his chief rival, former Arkansas Governor Mike Huckabee, to win the nomination, no matter how well he does in Wisconsin. But Huckabee has refused to quit, arguing that voters have a right to make a choice based on their own beliefs and principles, not on what party leaders say.

Huckabee says he represents conservatives who care about such issues as abortion, illegal immigration, and reduced taxes.

McCain has broad appeal, which could prove important in November's general election in a state such as Wisconsin, which has been a battleground in past elections. But many conservatives in his party object to more liberal positions he has taken on such issues as taxes and immigration.
