I don't think he's that much of a planner. He thought this was a funny way to troll Muslims, for the amusement of MAGA people with a low IQ and a sixth grade reading level.

But he also probably thought he wasn't committing any crime since he didn't actually fill out any ballot. He merely showed how someone doing what he did could conceivably have filled out a ballot he wasn't supposed to.

He didn't think about it enough to even ask a lawyer if his little scheme to demonstrate how vulnerable elections are is a crime. That's why I think he did it mostly for the LULz, while also providing red meat for the BillJohnson's of the world.
