I would be perfectly happy voting third party. I’m also incredibly aware of the risk of splitting votes under the current system. It happened, as an example, in a special election in Hawaii a while back when two Democrats each refused to back out of the race and the lone Republican took office with a plurality that was far from a majority. If there were a runoff, ranked choice, or similar system in place Charles Djou wouldn’t have stood a chance because few would choose him over the other Democrat.

Start with changing the voting system, then we can talk third parties.
