Democratic, Republican voter bases are more different than ever The abbreviated version? Older rural whites and white men without degrees are rushing to the GOP. Everyone else? Mmmm, not so much. Check this out: The Democrats have changed the most, as the mix of voters who support them has grown less white, less religious, more college-educated, younger and more liberal over the past decade, according to the study by the nonpartisan Pew Research Center. Republican voters, by contrast, more closely reflect the demographics of an earlier, mostly white, Christian America. In one regard, the party's voters have actually stepped slightly back in time — Republicans are less likely today than a decade ago to be college graduates, Pew found. That's a striking fact in a country that has steadily grown more college-educated.
