GOP presidential nominee Mitt Romney's wife, Ann, is heading to Michigan on Monday, raising the possibility of an eleventh-hour play by Republicans for the Democratic-leaning state.

Ann Romney will headline an event at the Park Place Hotel in Traverse City at 1:35 p.m., according to the Romney campaign. She is then expected to head south to visit a campaign office in Grand Rapids at 3:30 p.m.

History as well as recent public polling is on the Democrats' side in Michigan. The Wolverine State has not voted for a Republican for president since 1988, and most polls show Obama holding a firm lead over his GOP rival in the state, although one recent survey showed the race in a dead heat.

On top of that, both campaigns as well as outside groups have largely been absent from the state's TV airwaves.

Even so, the visit by Ann Romney suggests that Republicans may be taking another look at a last-minute play in Michigan — or at least are intent on making Democrats believe that they are. A visit by GOP vice presidential nominee Paul Ryan to the Pittsburgh area earlier this month similarly fueled speculation that Republicans were looking to mount an effort in Pennsylvania, another Democratic-leaning state in which the Romney campaign has not been airing ads.
