It’s apparently a hold over from olden times when good Christian farmers weren’t going to skip church to travel to the county seat and vote. So Monday is a travel day and Tuesday is when you vote. Or something like that.

Voting day and daylight savings time are the two immutable objects in American life.

Edit: and both are catering to farmers. Those and corn subsidies are the 3 immutable objects in American life, all catering to farmers.
