A look inside CNN's exit polls:
- Of the 13 percent of voters who were 18 to 24 years old, Ron Paul pulled in 21 percent support, third-highest. Probably a testament to how low youth turnout was and how Paul supporters will turn out no matter the weather or stakes.
- Very religious voters (visit church more than once a week) went for Huckabee, the regular churchgoers went for Romney, and those who never go to church went for McCain.
Romney did not dominate the economic pessimists as expected. Those who thought the national economy was good went overwhelmingly toward Romney. But among those who thought it was "not good" or "poor" McCain and Romney were tied for support.
Young voters (18-39) favored "Uncommitted" over Clinton. But that age subset made up only 32 percent of the vote. Older voters liked Hillary better, so she was the overall winner. This doesn't bode well for Hillary's youth-outreach efforts, although Michigan hasn't seen Clinton firsthand.
The more years of education people had, the more likely they were to vote Uncommitted. That may say more about Uncommitted-outreach efforts than anything else. Similarly, the margin between Clinton and Uncommitted narrowed among richer voters, although she still won in every income bracket.
White women: 70 percent of support for Clinton. Nonwhite women: 65 percent support for Uncommitted.
Also of note, the gender breakdown in the two parties is inverse: 56 percent of Democratic voters were female, 44 percent male. For the GOP: 56 percent male, 44 percent female.
