Decision time

(NBC News) As voters head to the polls today in five states a new NBC News/Survey Monkey national poll has Hillary Clinton up by 10 points over Bernie Sanders.

"I don’t accept there is no path for us," Sanders told supporters. "You know, let’s not count our chickens before they’re hatched.

Donald Trump hit 50 percent for the first time in the weekly tracking poll, as the other two Republicans agree to split up their chances against him in three upcoming states.

Ted Cruz is already going after Kasich supporters in Indiana.

"If you don’t want to see Donald Trump as the nominee, if you don’t want to see Hillary Clinton as the next President, then I ask you to join us," Cruz urged voters.

The Republicans will split 172 delegates today, still not enough to put any one candidate over the top.
