“Stop Trump’’ is the wrong theme; it will be inevitably seen as thwarting voters (“The GOP must stop Trump’’). A better theme is the more general one of stopping a candidate with high disapproval from winning a presidential nomination. For 2016, the only way to do that is a contested convention, but looking beyond that, we need a system that prevents a disapproved candidate from being the front-runner in the first place.

The reform of using “approval voting’’ would accomplish this. Instead of voting for one top choice from as many as 17 candidates, you vote for all candidates that you approve. A candidate such as Trump, with a low ceiling on approval, wouldn’t do well.

Our Founders designed an indirect way of electing a president. We’ve moved to a more direct system of voting, but it has a major problem. We need to fix this problem by using approval voting in presidential primaries.
