With Minnesota teetering on the edge of battleground territory in the presidential race, Republican nominee Mitt Romney and President Obama sent in their top campaign surrogates Sunday, expanding the field in the closing days of a wildly unpredictable contest.
After largely sidestepping Minnesota other than a brief dinner stop last week, Romney running mate Paul Ryan attended a "victory rally" at Minneapolis-St. Paul International Airport, holding out the prospect of ending the state's 36-year stretch of voting for Democrats in presidential elections.
Hours later, former President Bill Clinton touched down in St. Cloud to energize DFL volunteers and shore up a firewall of Midwestern states, including Ohio and Wisconsin, which could play a critical role in picking Tuesday's winner. It was his second trip to Minnesota in less than a week.
Furthering the impression of a swing-state battleground, the Romney campaign announced that one of the candidate's sons, Josh Romney, will attend an election-closing GOP rally in Plymouth Monday morning.
"I've got a question, Minnesota," said Ryan, a Wisconsin congressman, firing up an enthusiastic crowd of 10,000 at a Sun Country Airlines hangar. "Are you going to help us win this election? ... We can use your help."
The last-ditch push of presidential campaigning added to a daylong mix of debates in Minnesota, including a face-off between U.S. Sen. Amy Klobuchar and her Republican opponent, state Rep. Kurt Bills, before a live audience on public radio.
Clinton's visit to St. Cloud -- following trips to Minneapolis and Duluth last week -- also aimed at the heart of the congressional district represented by GOP firebrand Michele Bachmann, who is locked in a surprisingly competitive congressional race with DFL businessman Jim Graves.
While the two presidential advance teams set up their events in Minnesota, Bachmann and Graves engaged in a spirited verbal duel on KSTP-TV, the last of three encounters in less than a week.
