As the Michigan race entered its final days, McCain gained some notoriety by sending out mailers there and in South Carolina attacking Romney's tax record and touting his own. A Romney campaign spokesman called the ad "as sloppy as it is factually incorrect", and FactCheck.org called the piece "misleading". McCain responded by saying, "It's not negative campaigning. I think it's what his record is." "It's a tough business," he added. The dominant issue in Michigan was the state of the economy.

"Nothing could be further from the truth," Swindle said. "I know because I was there. The truth is, the North Vietnamese offered John McCain early release, and he refused." After that, however, there was little in the way of dirty tricks during the rest of the campaign. McCain won the South Carolina primary on January
