WASHINGTON (AP) — Donald Trump called for GOP unity after his Indiana primary victory Tuesday night, but exit polls suggest he's facing a significant intraparty rift. [...] half of those who voted for Cruz or Kasich on Tuesday night said they would not vote for Trump in the general election. [...] Democrats are largely satisfied with either of their top candidates, according to exit polls conducted for The Associated Press and television networks by Edison Research. The findings from the exit polls also show that Trump can thank male voters for running up the score against Cruz, who dropped out of the presidential race after his Indiana defeat. Overall, half of Republican voters say they feel betrayed by their own party leaders, but only a third agree with Trump's criticism that the GOP nomination process has been unfair. Just over half of self-identified Republicans and independents voted for Trump, as did 6 in 10 Democrats voting in the Republican primary, who made up about 5 percent of GOP primary voters. The survey was conducted for The Associated Press and television networks by Edison Research as voters left their polling places at 35 randomly selected sites in Indiana. The results among all those voting in each contest have a margin of sampling error of plus or minus 4 percentage points.
