A five-day, six-state bus tour by Republican presidential candidate Mitt Romney will wind up next week in his home state of Michigan.
Romney last visited Michigan in May.
The Michigan swing with three stops will cap off a tour of half a dozen states deemed potential battlegrounds by the Romney campaign.
A survey of voters released last week suggests Michigan could be a toss-up between Romney and President Obama.
The president has made almost a dozen trips to Michigan to talk about green energy jobs, or to proclaim the success of the automotive rescue package. His campaign will spend this week calling attention to businesses that benefited from the auto recovery. Romney – who was born in Detroit -- opposed government loans to keep Chrysler and GM solvent through bankruptcy.
