Uneducated whites don’t like Clinton.

“so many times white, non-college-educated white males have voted Republican. They voted against their own economic interest because of guns, because of gays, and because of God. The three ‘Gs.’”

—House Democratic Leader (and Clinton supporter) Nancy Pelosi

From the post-GOP convention CNN/ORC Poll:

Among white voters with college degrees, Clinton actually gained ground compared with pre-GOP convention results, going from an even 40% to 40% split to a 44% to 39% edge over Trump. That while Trump expanded his lead with white voters who do not hold a college degree from a 51% to 31% lead before the convention to a 62% to 23% lead now.

The “degree/no degree” populations aren’t the same size. There are 118 million white Americans 20 or over without college degrees, only 51 million (30%) with degrees.

Minorities (56 million 20 or over) are overwhelmingly with the Democrats. Whites without college degrees support Trump. The sharp, bitter divisions we see today are among whites with college degrees.
