(CNN) - More South Carolina Republicans say the economy is their number one concern than any other issue - but neither John McCain or Mike Huckabee have a clear advantage among these voters.
According to CNN exit polls, 40 percent of the state’s GOP primary voters named the economy as their top concern. McCain drew support from 31 percent of those voters to Huckabee’s 29 percent.
In Michigan, McCain's weakness among economy-minded voters compared to Mitt Romney was a major reason he lost that state. Michigan voters who said the economy was the most important issue favored Romney over McCain, 41 percent to 29 percent.
