In the — very unlikely — scenario that Trump leaves the race, the Republican Party would have the chance to name his replacement. Of course, some Democrats would just love it if Trump would drop out of the race even as his name lingered on the ballot. Donald Trump has had a very bad week, picking inexplicable fights with the parents of a fallen soldier, with war heroes, fire marshals and even babies. 'The democracy canon' ... holds that election rules should be interpreted as generously as possible in favor of voter interests. Many states have early deadlines for naming a replacement, so if Trump waits, say, another three weeks before withdrawing, some state laws may require his name to stay on the ballot.
