When was the last time the Republican party was actually the conservative party? That's the problem - it's not just the fact that the party isn't signing on new members. It's that the party has evolved (devolved) into "liberal-lite".
I left them 3 years ago for that very reason.
I left and came back in reaction to the then current political situation. I’d love to see every Conservative Republican re-register as an independent, just so the party could see how much displeasure there is out here in fly over country.
If the party only had 10% of the registered voters, it would shake it up dramatically. People could always re-register as a Republican before the primaries.
Right now, we’re being jobbed by the party leadership.
Then conservatives need to retake the party. What good has sitting on the side lines done?
