Due to the good work that both the state and county election officials have done to ensure short lines for voters
Of course this is the real answer, if it is true. It’s not just suffering in the heat that would make people disinclined to vote, but the line itself. Somehow I doubt they’ve really shortened the lines in places where “those people” vote.
I’ve never in my life had to wait in a line long enough to matter, since I live where we encourage people to vote. Of course it’s also a mostly white suburb, so I could be totally off-base
