The failing Stop Trump movement has led to an agreement between the other two active candidates to try and stop the billionaire. John Kasich will abandon his efforts in Indiana in a bid to deliver the state and its 57 delegates to Ted Cruz.
Meanwhile the Cruz campaign has agreed to stand down in Oregon and NM and let Governor Kasich attempt to deny those states to Mr. Trump.
Whether supporters go along is yet to be seen but the move was jointly announced by the two campaigns.
Mr. Trump is expected to sweep five states on Tuesday and was increasingly favored in the Hoosier State. Indiana is seen as a necessary step to deny Mr. Trump the 1237 delegates he needs for a first ballot win.
