In October 2006, the Creswell campaign spent over $10,000 on radio advertising, which while small, was the most spent on a such advertising by any Michigan gubernatorial campaign outside the Democratic or Republican parties. The largest investment was made in advertisements on Detroit AM Radio stations WJR and WXYT. These commercials specifically targeted Devos and Granholm by referring to them as candidates of "The two old parties," and berating them for supporting state-supported preferences based on race and sex: A clear reference to MCRI. Campbell spent less than $1,000, as was the case with the Dashairya campaign.
