McCaskill Bus Tour in Columbia
About 200 people turned out, including local college and university students.
"It's always nice to come see her and see what she has to say to rally us," said Nate Kennedy of College Democrats.
McCaskill talked about Proposition B, which would raise Missouri's minimum wage to $6.50 an hour if voters pass it on Nov. 7.
"I think it's important that we're the wealthiest nation in the world and, you know, it's embarrassing that $5.25 or $5.15 is our minimum wage," she explained.
McCaskill hopes her latest swing across the state provides a final push before next Tuesday's election.
"There is such an energy out here, you know, there is a certain momentum," she said.
"It's a close election," Kennedy added. "We need all the help we can get."
Some of that help will come from Illinois Sen. Barack Obama, who will campaign with McCaskill at another get-out-the-vote rally this Sunday in St. Louis.
On Friday, President Bush campaigned in Springfield for McCaskill's opponent, Republican incumbent Jim Talent.
