Not as crazy as it seems. This Death Spiral of the GOP is far more serious than the problems the Dems had with their crazy Left. If the Repuboicans don't shake out of it somehow then there may be an opening for a real Center-Right party to emerge.

This leads to an opportunity for a new Party to emerge. What that will look like is very unclear right now, but we should not kid ourselves as Democrats that our electoral victories are all due to the public wanting to do things our way. When your choices are a Party you disagree with most of the time and the bat-shit insane, well that is not really much of a choice, is it?
