While I don't disagree, there's also the problem of their base dying of old age and not being replenished through birth or immigration. I almost shared this this morning but in the end, didn't find it quite insightful enough, despite the fact that the author's Columbine book has been on my watchlist since 2008 or so.
If you're turning 18 this year, Ruby Ridge was 5 years before you were born. You were two when Columbine happened. Obama has been your president since you were 11. Your teenaged years have been marked by a gradual return from recession under a black Democratic president and both gay marriage and weed are soon or have been legalized. Yeah, you can be a dead-end burnout hater-of-progress but even deep in the Ozarks it's not hard to find evidence of things going in a positive direction under the party of Not-Reagan.
Combine that with the fact that whites are becoming a minority, immigrants are getting legalized and the Republicans are chasing away everybody that isn't white or doesn't accept Jesus Christ as their personal lord and savior and they're already facing eroding demographics. That's bad enough.
But when the Merchants of Death have decided the Republican Party is bad for business, things start getting interesting.
