How Huge Voter Turnout Eluded Bernie Sanders on Super Tuesday [View all]
In no state did people younger than 30 account for more than 20 percent of the electorate, based on exit polls, and in most states they accounted for 15 percent or less.
Because so few young people voted, it did not matter that Mr. Sanders won them by huge margins, because Mr. Biden won the much more plentiful older voters.
In addition, while Mr. Sanders has succeeded in galvanizing Latino voters he won them by about 27 percentage points over Mr. Biden in California he has struggled to build support among black voters.
In Alabama, where black voters were half of the electorate, Mr. Sanders lost them by more than 60 points. He lost them by more than 50 points in Virginia, and by more than 40 points in Texas and North Carolina. In several states, he came in third among black voters, behind not only Mr. Biden but also Michael R. Bloomberg.
In Minnesota, Mr. Sanders had a large gender gap. He had the support of 37 percent of men, according to exit polls, very close to Mr. Bidens 39 percent. But he only won 25 percent of women, compared with 41 percent for Mr. Biden. Mr. Sanders did do unusually well among black voters, who were a point of struggle for him in other states: He won 43 percent of them. But he only won 27 percent of white voters, who account for most of the Minnesota electorate.
