Hillary Clinton greets patrons Sunday at a San Juan, Puerto Rico, bakery."](CNN) - It was a clean sweep for Hillary Clinton in Puerto Rico in every demographic group, even those groups that are usually firmly in Barack Obama's camp.
The Illinois senator usually wins among males, young voters, those who attended college, and those with higher incomes.
But in the Puerto Rico primary, Clinton won 70 percent of the male vote, 65 percent of voters under 30, 70 percent of voters who attended college, and 66 percent of voters with an income of over $50,000.
Clinton also performed strongly among those demographic groups that have long constituted the backbone of her base.
She won 70 percent of female voters, 77 percent of those over 65, 69 percent who did not attend college, and 71 percent of voters with an income of $15,000 or less.
