Damn it. I should have looked more closely. 😔 I flipped it over and glanced to make sure I heard correctly about "only the front", and there was nothing on the back for voters. In the bottom, I don't know, maybe fifth? of the page was an outline box with print and lines and boxes, but it was 'official' type stuff and I didn't bother to see what. (I think maybe district/ward stuff like my slip?) I just wanted to get out of the public and home to my solitude

It was like u/Tropism said, nothing for the voters on back. The bottom fifth was just the part where whoever checks them or validates them, maybe for absentee or after the election is done or if a machine can't read it?
