I'm a libertarian (small L). I tried infiltrating my county Republican party and was even a county and state delegate for several years.
I gave up. Jeb Bradley and Charlie Bass are RINOs and they are going to keep winning. If I mount a successful attempt to curtail their votes, a Democrat will win. Dick Swett was our Senator the last time we tried that. Big mistake.
We (small L libertarians) are a small minority. When we stray from the more conservative of the two parties, we simply guarantee the liberals will win.
It's a Hobson's choice... Democrats or RINOs?
Never give up.
