No - conservatism isn’t dying out. Neither is republicanism. We’ve had a set back, just like the democrats had a setback when GW was elected.
Give it 4 years - maybe 8 if O does spend us out of a recession, and we’ll be back.
The pendulum will keep swinging.
Unfortunately, you don’t fully understand just how bad it’s really going to get for all non-leftists in the future! Leftists will also allow as many criminals as possible to vote in all future U.S. elections, and leftists will also allow illegal immigrants to vote in all future U.S. elections. Non-leftists really don’t have an equal number of voters to match these newly created “pro-leftist” voters. Also, the “dumbing down” of people continues to get even worse everyday, and all political correctness, on all of the issues, also is getting worse for everybody everyday. There will also be even more ignorant voters and even more stupid voters during every future U.S. election. All non-leftists don’t have any kind of serious chance to successfully get around all of these problems for them.
