<Nothing whatsover to do with stupidity.

Of COURSE it's stupidity. Pencil-neck, butt-ignorant stupidity. Could you locate a single voter who would stand up and say, "Oh, yeah, I bought this based on a Xeroxed sheet I found on my windshield." Did anyone ever locate such a voter?

Thanks for sidestepping the issue that it was likely a republican supporter (you know, those principled ones who
always run fair elections) who pulled this kindergartener trick.

Or a Democrat trying to trump something up for a possible court challenge. Easy: just put out a flyer that he knows nobody with any reasonable brains would fall for, so it would cost no Democratic votes, but it would do the job nicely of corrupting the idea of a fair election.

My scenario is as plausible as yours.
