I'm certainly not talking about everyone, my point is that these ideas are not as appealing as the party once swore they were and I think what we are seeing in our politics today is a reckoning on what to do about that.
I'm not entirely sure that social conservatism isn't viable politically, but I know that the fiscal libertarianism definitely isn't viable. Hispanics, the largest minority voting block, are quite religious and socially conservative overall. If the GOP would become a populist conservative workers party, I think they would keep all of the White vote they need while also gaining large portions of the Hispanic vote.
We operate more or less on a pendulum. The widespread degeneracy we are seeing is very likely to have a strong reaction as people can no longer stomach what our culture has become. While Hollywood and the media do everything they can to make conservatism seem "uncool", you have to realize that the GOP has never been the young person's party. It is the party of families, evident as most married people with kids vote for them.
But I certainly agree that the GOP has cast aside most of its socially conservative principles in what Patrick Buchanan more or less describes as a neocon insurgency. Neocons are free traders, social liberals, and war hawks that must be cast out of the party before it can once again become competitive nationally.
