What’s the surest way to prevent Donald Trump’s opponents from re-writing the GOP’s rules to deny him the nomination at next month’s convention? According to a new proposal from Republican National Committee member Solomon Yue, the answer is simple: Don’t allow any new rules adopted in Cleveland to take effect until the 2020 convention.

The GOP’s rule-writing process is relatively straightforward: Every fourth summer, in the days prior to the party convention, an elected body known as the Convention Committee on Rules and Order of Business approves a package of rules. Once ratified by a majority of delegates on the floor, this language governs the convention and, for the next four years, the party.

Between conventions, the rulebook is reviewed by the RNC’s Standing Committee on Rules, which debates changes and approves recommendations to be taken up by the next Convention Committee on Rules and Order of Business. (The groups are separate but members overlap; call them the Convention Rules Committee and the RNC Rules Committee.)
