Yeah, there is a little known clause in the Bill of Rights that states if you don't for a Democrat or a Republican, you are throwing your vote away. Also, if you don't embrace one of the top two religions, your soul will be cast into eternal damnation.
No such thing, and certainly not veering into religion therein. But if one chooses to vote, then chooses a Republican ballot, then chooses to vote as opposed to leaving that section of the ballot unmarked, then chooses to vote that none of the above candidates are acceptable, then I think one is throwing his or her vote away.
