Trump wants Kasich out of race as Wisconsin vote looms

Americans return to the polls for yet another presidential primary election in what has proven the most chaotic Republican contest in recent memory, with front-runner Donald Trump now pushing rival John Kasich to leave the White House race saying the nomination is beyond his grasp.

Trump, who is badly trailing Texas Sen. Ted Cruz in the polls ahead of Tuesday's primary in the Midwestern state of Wisconsin, argues that Kasich is unfairly siphoning off delegates who will select the party's candidate for the November general election.

Trump holds a significant lead over Cruz in primaries and caucuses so far, but looks as though he will be unable to gain the 1,237 delegates needed to lock up the nomination ahead of this summer’s national convention in Cleveland.

Trying hard to right himself after a difficult week, Trump said it was unfair for Kasich, who has won only one primary in his home state of Ohio, to continue campaigning. He suggested that Kasich, who has pledged to make it to the convention, follow the lead of former candidates Marco Rubio and Jeb Bush and quit.
