Ann Romney set to visit Milwaukee

GOP rally to be held at Marquette University

Republican presidential hopeful Mitt Romney’s wife is expected to visit Milwaukee later this week.

Ann Romney is set to appear at a GOP rally Thursday at Marquette University. Doors open at 9:30 a.m. The event is slated to begin two hours later.

The visit underscores again how Wisconsin has become a key battleground state in the November election.

Her husband’s running mate, U.S. Rep. Paul Ryan, hails from Janesville and held a campaign event near Green Bay last week.

Vice President Joe Biden has visited the state twice in the last month.
