In Trump’s home state of New York, however, Trump has a dominant lead over the field, 52 percent to 21 percent for Cruz and 20 percent for Kasich. The billionaire leads by wide margins as best to handle multiple issues including terrorism, bringing back jobs, and the ability to defeat Hillary Clinton if she is the Democratic nominee.

And in Pennsylvania, coming up at the end of April, Trump also enjoys a strong lead at 47 percent while Cruz and Kasich are well back at 29 percent and 22 percent respectively.

All these contests, in particular Wisconsin’s, highlight the divisions among voters in the Republican party. Many of Trump’s voters are not only strong supporters, but say they are Republicans who have been interested in this primary mainly because of Trump. On the other side, most Wisconsin voters who are not backing Trump would like to see the party try to stop the businessman at the convention, even if Trump continues to win primaries.
