MADISON, Wis. (AP) — If there is a fight at the Republican Party convention this summer over who will be the presidential nominee, delegates from Wisconsin may find themselves on the sidelines. That’s because unlike in other states, Wisconsin Republican Party rules make it difficult for the 42 delegates to break from supporting the candidate they are pledged to back. Wisconsin is likely to become a focus for the three remaining Republican candidates starting next week, after primaries on Tuesday in Arizona and Utah. There are 42 delegates at stake in Wisconsin’s April 5 primary, a fraction of the 2,472 who will gather in Cleveland for the national convention. Donald Trump, Texas Sen. Ted Cruz and Ohio Gov. John Kasich are the three remaining GOP candidates.
