The networks instantly called the Kentucky primary for Hillary Clinton as the last polls closed on the western side of the state. A glance at the exit polls shows why and how Clinton won so decisively.

Clinton won every age group, all income levels and both genders by large margins. Clinton won 55% of 17-29-year-olds who have regularly voted for Obama, as well as three-fourths of those 60 years and older. Clinton won three-fourths of white voters, who made up about 90% of the electorate. Church attendance had little to do with voter decision-making, as Clinton won two-thirds of church-goers, as well as two-thirds of non-church goers.

Clinton won at least 62% of all who describe themselves as either liberals, moderates or conservatives. Of the 86% who said the recession has affected them, Clinton won two-thirds. Nearly 60% of the electorate lives in rural areas, and Clinton won three-fourths of those voters. And like West Virginia, more than half of voters felt Obama shared the views of his former pastor, the Rev. Jeremiah Wright. Clinton won 84% of those voters.

Most voters made up their minds well before either candidate campaigned in the state. More than 70% said they had decided their choice more than a month ago, and 68% of them chose Clinton.
