MINNEAPOLIS — First lady Michelle Obama is the latest prominent figure to come through Minnesota to fire up Democrats.

Obama was to appear at a Minneapolis high school this afternoon for a get-out-the-vote rally with Gov. Mark Dayton and Sen. Al Franken, who are seeking re-election.

Both parties are trying to mobilize voters in the campaign’s waning weeks, bringing in politicians like former Democratic President Bill Clinton and New Jersey’s GOP Gov. Chris Christie.

Republicans are using the first lady’s visit to make the case that the incumbents are too close to a president with waning approval ratings. President Barack Obama was last in Minnesota in June.

Franken and Dayton both lead their races in independent polling, but Republicans are banking on a national mood and turnout trends favoring them.
