If you want them to win, you should encourage them to caucus with and run as a member of a party that can win.
Any effort put into 3rd parties is a waste of resources because they can’t ever win in our system of government. You can wish for things to be different, but wishing doesn’t accomplish anything.
Are you suggesting that famous people from outside the party should be placed at the top of the ticket?
Good leaders spend a long time building experience. Someone with a strong legislative, judicial, or executive record should be the candidate. Not some reality TV star or shitty actor. We’ve done that enough in my lifetime.
So yeah, the candidate should be someone that’s been with the party for a long time, and that’s why it’s so important to get involved and vote in local primaries and elections so that the kind of candidate you want to support is the one that’s been working their way through party leadership for 20 years.
