Yeah I actually think this is mostly true, in which case I think it is better to spoil your ballot in most states (I am assuming that these get counted in the US which I am happy to be corrected on if false)

Because you are an unserious clown/troll

If by "counted" you mean people mark that there's been "x invalid ballots" then yes, probably. If by "counted" you mean "there is any chance of it having any effect on the outcome of the election," the answer is "no" like in most places.

what does this accomplish
