Wisconsin treasurer Sarah Godlewski drops Senate bid

Wisconsin Treasurer Sarah Godlewski dropped out of the state's Democratic U.S. Senate primary Friday, clearing the path for Lt. Gov. Mandela Barnes to win the nomination on Aug. 9. 

Barnes is going to be the party's nominee to take on Republican Senator Ron Johnson, a top target for Democrats this year. 

Godlewski's departure is the third notable Democratic candidate to drop out and endorse Barnes in the last week. County executive Tom Nelson and Alex Lasry, an executive of the Milwaukee Bucks basketball team, dropped out earlier this week.
