In my middle class neighborhood is a solid YES too. (Broadview Heights, Ohio).
The poll workers said they got slammed between 6-7 a.m. (working folk)
I just got back from voting at 4:00 and I was #360 at my polling place. Didn’t seem any crowded than usual. Did see one union smoker using the ash tube thingy outside the polling place door and I told him to get back from the entrance.
