My point is that if you want to win in a first-past-the-post voting system, if you can’t get everyone to vote for your candidate the next best thing is to stop your opposition from showing up. Common tactics are limiting who has access to polling places, purging people from voting rolls, adding barriers to registration, and sabotaging mail-in ballots, but you can also encourage apathy, purity testing or erode faith in the electoral system, all of which work to allow a party with a minority of supporters to win an election.
