33% (R) - 37% (D) - 23% (I)
29% (C) - 38% (Moderate) - 15% (Liberal)
The most damning: 44% College Graduate. Although both categories here poll equally.
56% college grads is definitely an overestimate, but they're probably also overestimating McCain's performance among them. (The usual paradigm is that the best group for Republicans are those with some college or only a bachelor's degree, but those who have college degrees includes the very Democratic groups with Master's degrees and higher and generally favors the Democrats as a whole.)
All of this is complicated somewhat by race, though, so the paradigm is more easily applied in very white states and less so in states with large black or Hispanic populations, like Virginia.
