Fox News:美国总统选战候选人展开你争我夺

Delegates are what all the candidates are scrambling for.
Going into today's contests, Ted Cruz had 300 delegates, behind Donald Trump's more than 380.
This evening, Cruz will be at a church in a Charlotte suburb.
Tonight's event is another chance to talk to the evangelicals that could keep him in the race.
Trump will campaign in Florida, as the candidates are turning their attention to next week's elections in Florida, Ohio, and right here in North Carolina.
In Charlotte, North Carolina, Tonya J. Powers, FOX News.
