The problem is not the GOP; the problem is the opposition. The GOP is outvoted. It needs to increase its percentage of one of the demographic groups and there is no sure solution. When Reagan won in 1980 vs. Romney loss in 2012, the demographic makeup of the voters was:
We lost the Republic demographically.
You nailed it. It is gone, probably forever.
The minorities in this country now reflexively hate us and will always vote against us. Whites will continue to drift our way, but at much too slow a pace to overcome the rapidly growing Hispanic and Asian populations.
All that is left now is to watch the economy crash and burn, and to try to avoid (or fight) the religious persecution that is most assuredly coming our way.
The only slight satisfaction I will take is in watching the white liberals eventually being swept away as well and becoming hated just as much as we are.
