Spoken as one who has never worked at the polls.
Shift workers and people who have an early day tend to vote on their way to work. In the case of people coming off midnights, they tend to vote on the way home.
Farmers tend to vote early. They get up before the sun. 7:00 AM is already late.
9-to-5ers about split down the middle. People like my dad, who's an early riser, take the time in the morning.
The unemployed sleep late. Why do they need to get up?
Please check your reality against the reality of working people.
