A congressman from neighboring Wisconsin, Ryan played to the Minnesota audience. He pointed out a "Vikings for Romney-Ryan" sign in the crowd and noted he is often mistaken for a Minnesotan.
"We're the Catholic deer hunters. You're the Lutheran deer hunters," Ryan said.
Jeff Blodgett, the Obama campaign's Minnesota director, said at the Clinton event he thought Republicans were overstating Romney's chances of taking the state, which hasn't gone for a Republican president since 1972. But he also acknowledged that Obama can't afford to lose the state.
"It's a must-win state for the president," Blodgett said.
Devin Johnson, a St. Cloud State philosophy major and Obama supporter, said he was feeling good about the president's chances with the election days away. "The most important thing right now is to not lose the momentum," said Johnson.
Tom Fisher, a St. Cloud resident at the rally, described himself as more liberal than Obama but said at this stage of the race he's dropped any reservations about supporting him.
"If it's a choice between someone trying to do the right thing, and someone who'll do worse than nothing, I'll take Obama," Fisher said.
