$100,000
Exit polls in both Michigan and Ohio show voters making more than $100,000 per year turning out in much higher numbers this year than they did in 2008. In 2008, 22 percent of GOP primary voters in Michigan made at least $100,000, and that group made up 21 percent of the electorate in Ohio, according to exit polls. This year, 33 percent of voters in Michigan made that much money, while 30 percent of Ohio voters did. In both cases, the number of wealthy voters grew by about 50 percent — a pretty stunning increase in that demographic over just a four-year span.
