Trump leads big in Indiana state primaries: Poll

Washington, May 2  Republican front-runner Donald Trump has a double-digit lead over party rival and Texas Senator Ted Cruz in the Indiana state primary on Tuesday, according to a new poll.

The new joint poll conducted by the Wall Street Journal, NBC News and Marist College, says Trump leads Cruz by 15 percentage points in Indiana, 49 percent to 34 percent. 

Ohio Governor John Kasich is last at 13 percent, Politico reported.

Cruz is hoping for a win in order to continue preventing Trump from securing the party nomination before the Republican National Convention in Cleveland. 

The Democratic race is a bit more competitive. Front-runner Hillary Clinton leads Vermont Senator Bernie Sanders, 50 percent to 46 percent, among likely Indiana primary voters.

The poll, conducted from April 26 to 28, included 645 likely Republican primary voters and 449 likely Democratic primary voters. 

It has a margin of error of plus or minus 3.9 percentage points and 4.6 percentage points, respectively.
