Campaign dollars pouring in: Focus on Wisconsin in bid for White House, Senate control

MADISON— Millions of campaign dollars are pouring into Wisconsin starting Monday, October 31st for the final week of the election.

Democrats are looking to push Russ Feingold over the finish line in the U.S. Senate race against Sen. Ron Johnson. It's one of the key races nationwide that could determine whether Republicans retain majority control.

Donald Trump heads to Wisconsin Tuesday, November 1st, as does Hillary Clinton's running mate, Tim Kaine.

Johnson has long been seen as one of the most vulnerable GOP Senate incumbents this election cycle. But his campaign has argued the race is tightening and that Democrats were spending money late because they were getting nervous.

Democrats have been counting on a Feingold win in Wisconsin as they eye retaking control of the Senate. They must pick up four or five seats to do so, depending on whether they retain control of the White House.

Both sides hit the airwaves with a late advertising push Monday, October 31st.
