McCaskill Stumps in Columbia
McCaskill said she chose Sutton's because it represents what's important to her campaign, especially raising Missouri's minimum hourly wage.
McCaskill also criticized Republican incumbent Jim Talent for what she called his personal attacks against her.
"It obviously hasn't worked because, if their commercials were working, nobody would be voting for me," she said.
President Bush stumped for Talent in Springfield on Friday.
McCaskill headed to St. Louis Friday night, where Illinois Sen. Barack Obama will campaign with her this Sunday.
