MADISON, Wis. (AP) -- The leading Democratic candidates in the race to take on Republican Gov. Scott Walker in a recall election next month are making their final campaign stops before Tuesday's primary.

Milwaukee Mayor Tom Barrett planned stops Monday in Sheboygan and Kenosha. A Marquette University poll released last week showed him with a 17-point lead over Kathleen Falk, the former Dane County executive who is the favored candidate of the major unions that helped spur the recall against Walker.

Falk planned to spend the final day before the primary campaigning in Milwaukee.

Two other Democrats running are Secretary of State Doug La Follette and state Sen. Kathleen Vinehout. They have failed to gain traction in the race.

The winner will move on to the June 5 general election.
