(CNN) - CNN just called the Pennsylvania primary race for Hillary Clinton. How did she win?
Her clear support from white voters and women. Both groups constituted large majorities in Tuesday's primary, and both voted for Clinton handily.
Whites made up over 80 percent of Pennsylvania Democrats. Clinton bested Obama among those voters by 20 points, 60 to 40 percent.
Women also constituted a clear majority of Pennsylvania primary voters – 56 percent. They voted for Clinton by a 12-point margin, 56 to 44 percent.
Another reason Clinton won? She beat Obama easily among late-deciders. Those voters who decided in the last three days went for the New York senator by a 15-point margin, 57 percent to 42 percent.
