JFK didn't just wear shirts on TV.

He managed to convince the dead in Cook county, Illinois to vote for him, often several times each! I'd consider that a much more impressive first. It eclipses hanging chads and Russiagate in more recent elections. JFK won the election because Nixon conceded even though there were plenty of suspicious circumstances - more than enough to justify challenging the results of a very close election.

Today the people have so little faith in the system and in the candidates that almost half of them don't vote.
