This is a tough one. He used Hillary Clinton campaign logos. If you were to put up flyers that you could mail your vote to a physical address I can see that being easily prosecuted. The difference here seems to be the ease in which the joke is made.

The problem/s is the unequal use of the law. Because libtards did it to. And also that there is no proof someone actually lost a vote because of it. So without a victim I don't see why he would be prosecuted.
