Romney-Clinton-Biden voters are suburban, middle-class to upper-class, and moderate on social issues.
Obama-Trump-Trump voters are rural or ex-urban, lower-middle class to middle class, conservative on social issues, and have less formal education.
How about Romney-Clinton-Trump voters?
My best guess would be higher income Latinos. Especially among Cubans, since Clinton did better than Obama and Biden in Miami Dade.
I think 'high income Latinos' better describes
Obama-Clinton-Trump voters.
Romney-Clinton-Trump voters are probably white suburban conservatives who decided Trump wasn't as bad as he was made out to be.
