Just over half of Republican voters in five states said they'd be happy if Trump were the candidate chosen to run against Hillary Clinton in the general election, but four in 10 voters said they would seriously consider voting for a third-party candidate.

Notably, about six in 10 of non-Trump supporters said they would seriously consider voting for a third party if he wins the GOP nomination.

A new question added to the exit polls this year directly measures intent to vote for Trump, Ted Cruz, Marco Rubio or John Kasich in the general election. Across the five states voting today -- Florida, Illinois, Missouri, North Carolina and Ohio -- slightly more than half of Republican voters said they'd definitely vote for Trump, while about 20 percent said they'd "probably" vote for him.

About a quarter of GOP voters said they would not vote for Trump, according to preliminary exit poll data.

Fewer than 48 percent of voters saw Trump as "honest," while 62 percent of voters who said they were looking for an "outsider" supported Trump.

Trump also won 45 percent of votes supporting the deportation of undocumented immigrants, rather than offering them a chance to apply for legal status.

Of the voters who described themselves as "angry," Trump won 42 percent of their support, according to preliminary exit poll data.
