America's diploma divide: States with fewer grads went for Trump

One factor with a startlingly strong record of predicting whether a state voted Trump or Harris: the percentage of their population that graduated college.

Why it matters: America has split, and flipped, by education levels. Democrats have largely lost the working-class voters who elected Barack Obama, and college-educated professionals are shifting away from the Republican Party.

Now those with degrees overwhelmingly back Dems, and those without make up most of the red base.
