RECAP: Johnson, Barnes get personal in final Wisconsin debate

Republican U.S. Sen. Ron Johnson and Democratic challenger Mandela Barnes got personal in their final debate Thursday before the Nov. 8 election, with each candidate attacking the other as being a liar, radical and out of touch with the average Wisconsin voter. Johnson, who is seeking a third term, and Barnes, the lieutenant governor, are locked in a tight race that could determine which party controls the Senate. The debate in Milwaukee came a day after a Marquette University Law School poll showed Johnson with an apparent lead, marking a steady increase for the incumbent since Barnes won the Democratic primary in August.
