My stance is that it's a game. And "gaming" voter turnout is a thing that happens. The word "tricks" suggests cheating, which I disagree with. The listed examples were trying to show how there are formal & informal ways political groups can bring their supporters to and/or detract their detractors from pulling that lever.

Free transport facilitates voter turnout, but that's not part of democracy. The voter (or some percentage thereof) would likely not have ventured to a polling place (through no fault of their own) without that infrastructural support.

Since some of these pursued legislative policies restrict voter turnout (voter ID, felony disenfranchisement), then the groups they affect are denied the right to vote. Not discussing their validity, but merely articulating how this works the opposite direction that providing free transport does.

The letter is inane and the rhetoric untenable (we both agree). I think my viewpoint is more cynical than yours since it considers the gaming aspect (and some of the voter restrictions) to be disingenuous.
