I don’t like TV ads, mailings, etc. that encourage people to vote. If I had money to burn, I’d buy advertising with the opposite message: please don’t bother voting.
Reason 1: When more people vote, the impact of my single vote is diluted.
Reason 2: When fewer people vote, the impact of my vote increases.
Reason 3: If, hypothetically, my “please don’t vote” campaign convinced everyone else not to vote, I still would vote, and then I’d get my way — for everything on the ballot. =D
