Voting third party is not really a viable strategy until we change the FPTP voting system. You aren’t going to fix this by attempting to vote for a third party in the upcoming presidential election. If you want change in the system, you have to start from the bottom and work in local elections and then state elections to get them to change the voting system. Then we can have viable multiple parties. But this “we can vote out the POTUS in the next election!” is theoretically possible, but it’s also painfully naive in reality.
