When President Obama returns to Chicago for his 2012 election night rally on Nov. 6, it turns out he'll be arriving just on the heels of yet another big-ticket Windy City fundraiser for the president's Republican challenger Mitt Romney.

According to the Chicago Tribune, Romney's camp will hold its final Chicago fundraiser ahead of the election on Nov. 2 at the home of Ron and Christina Gidwitz in the city's Gold Coast.

Though Romney will not be present at the fundraiser, the Tribune reports that Virginia Gov. Bob McDonnell and Wisconsin Sen. Ron Johnson will both be on hand. Senator Mark Kirk, Illinois state Treasurer Dan Rutherford and all nine House Republicans seeking re-election this fall are also listed as event co-hosts.

The Chicago Sun-Times' Lynn Sweet notes that the event is expected to raise some $1 million toward buying Romney ads in battleground states on top of at least $20 million Republican donors in Illinois have contributed to the Romney campaign since the March primary.

Obama, meanwhile, is slated to cast his ballot early on Thursday in Chicago. In so doing, he will become the first president to vote early.
