Maybe a little bit, but I think what happened was the GOP lost the Reagan Democrats. posted a bunch on this topic will not repeat again. I think single issuer and stay at homers did not account for much.
The GOP-Reaganites live in the past; knowing never when to apply those principles, always seeming to show up at all times to denigrate the Party of Reagan, in this day. Because they are the "real conservatives", they say.
