A bit more information...

I found this yesterday and thought it was an appropriate addendum to the previous post.

Republican Base Heavily White, Conservative, Religious from Gallup

While I am not a Republican, nor do I play one on TV, I am very concerned with the lack of outreach. If these trends continue, combined with closed primaries, the Republican Party is going to be dead within four-to-six years.

This is not good news. Democracies only function when there are peacefully competing groups vying for power and mindshare.
