Congress should convert the Thurmond Rule from an urban legend into actual legislation, settling on a specific set of criteria for closeness to a presidential election. For example, ACB was nominated 38 days from the election (the shortest distance from the election in history). One criteria could be to look at early voting dates. In South Dakota, that was Sept. 18th, which means that I could have already voted before Barrett's nomination. So one possibility would be to say that no nominations can be made after the earliest states begin voting, which would provide a fairly rational demarcation point.
