Nothing. Especially if you live in a state like Maine. However, by quitting when they did, it makes them look like they are trying to sabotage the MEGOP. That hurts their friends still in the MEGOP. It also helps are future liberty lovers that run for anything in the MEGOP for a few years, because people will be bitter. And it is very odd, considering some of them just won office, and even more, they were actually making impressive inroads. From the outside looking it, it looks like they wanted instant gratification. When they couldn't get it, they took their ball and went him.
Many of us have been working within the GOP for years and developed strong relationships. They folks, from the outside, appear either amateurism or short sighted.
I could be COMPLETELY WRONG and I'm not trying to hate on these people as individuals. They are likely good people but this is exactly the opposite of what liberty folks should be trying to do if they are trying to influence others in the GOP. I've found the GOP where I live extremely welcoming. It's a night and day difference, I guess.
