While Mitt Romney tonight over-performed among the groups he struggled with in Iowa -- conservatives, Tea Party supporters, evangelicals -- he didn't fare as well among middle-class and lower-class GOP primary voters.
According to the exit polls, Romney got 51% from those making $200,000 or more, and he got 45% among those making between $100,000 and $199,999 -- higher than the total 36% where he currently stands in New Hampshire.
But among those making less than $30,000, he captured just 31%. And among those making between $30,000 and $49,999, he got 32%. And among those making $50,000 to $99,999, he got 35%.
