They'd do better to meld with the Texas GOP and pull the GOP to the right.
Not possible. To many bribes and buy outs from special interests in both main parties.
Has the GOP listened to its core the last 10 years?
How many former democrats are now members of the GOP?
No offense, but where do you think most of these people come from? I have been attempting just what you suggest for 2 decades. To what ends? How much of a "right" turn has the Republican Party made? No, both National Party's have set themselves up to feed from the trough, and make it quite clear, vote for us, doesn't matter which one of us, then sit down and STFU! Thanks, but I've had my fill!

I once believed as you do though, hence the no offense intended preface to my post. Blackbird.
