President Trump’s political advisers have concluded a monthslong effort to tighten the rules for choosing delegates to the Republican National Convention, all but ensuring there are no dissenting speeches at the gathering of party officials in Charlotte next year.

On Tuesday, state Republican parties submitted to the national committee their delegate allocation plans, the methods by which they will choose and bind delegates who attend the convention as their representatives.

In 37 states and territories, there have been changes to the rules that will all but stamp out the possibility of any raucous divide on the convention floor. Those kinds of schisms have plagued party conventions in years when a Republican incumbent went on to lose his re-election bid, Republican officials said. Mr. Trump himself confronted an effort to strip him of delegates in 2016.
