Pubs aren't going to do that, it's the moderates and liberals who will create the impression that this most loyal base of the party is not wanted. The Pubs moved left after 2006, when they lost the House. They lost the House because they mishandled the illegal immigration issue, they didn't control spending and they let the Rat infested media control the message.
Bush was right about a lot of issues, but never had the stomach to fight for them and the House Pubs didn't either.
We need fighters who can keep their eye on the finish line. The opportunity to reform the party has never been better. The question is how.
There comes a time when a man recognizes he’s not welcome at certain gatherings. He stops attending.
Spend a few minutes reading up on what happened to the Whigs in the 1850s and the answer becomes fairly clear.
The Whigs couldn't agree on slavery (which, but for the slaughter of 50 million babies, would be the most critical social issue in American history), so the anti-slavery social conservatives left and formed the GOP. Within a few years the Whigs had disappeared and the GOP became the dominant party for decades.
Republicans could win if they focused on fiscal responsibility, cracking down on illegal immigration and crime, and protecting the Second Amendment.
The pro-life argument mobilizes the social conservatives, but it mobilizes the Left even more if they can give the impression that Republicans will outlaw abortion.
