Clinton, Trump look to extend their leads

Voters in a dozen states go to the polls — or in three cases, caucuses — on “Super Tuesday” in the presidential primaries.

What’s at stake?

The nominations of Hillary Clinton, in the Democratic race, and Donald Trump, in the GOP race.

To win, Trump needs 1,237 delegates. He has 82 to 17 for Ted Cruz and 16 for Marco Rubio. Almost 620 delegates are on the table Tuesday. The biggest prize is Texas with its 155 delegates, followed by Georgia at 76 and Tennessee at 58.

On the Democratic side, Clinton needs 2,382 delegates. She already has 543 to Bernie Sanders’ 85, a lead largely due to the support of super-delegates. However, almost 1,000 more delegates will be decided Tuesday. The biggest prizes are: Texas, 252 delegates; Georgia and Massachusetts, 116 each; Virginia, 110; and Minnesota, 93.

GOP keys to watch

▪ Texas, where Texan Cruz leads, according to recent polls

▪ Oklahoma, where Cruz has a narrow lead as well

▪ Minnesota, where Rubio could win his first contest in a caucus

In the eight other states, Trump leads, according to polls. He could exit the evening with about 200 more delegates, putting him a quarter of the way to the GOP nomination.

Democratic keys to watch

Colorado, Massachusetts, Oklahoma and Minnesota. Clinton leads in all, according to polls. But the leads are narrow — in Massachusetts and Oklahoma. Also, Sanders will win his home state of Vermont.

Of 11 “Super Tuesday” states, Clinton leads in 10. In addition, Democrats who live abroad and in American Samoa will weigh in.

Clinton should exit the night with at least 600 additional delegates, putting her at more than 1,100. Sanders should get about 400 delegates and a huge math problem.

To win the nomination after Tuesday, Sanders would have to win 60 percent of the delegates in every upcoming primary and caucus, including more than a dozen states were he trails in the double digits, according to polls.
