The "right" has simply given up. Look at how the media portrays anyone with "traditional values". Turn on any HBO show to get a glimpse of the condescension (True Detective??). Attempts to shut down Chick-fil-A in various states. Courts that overturn propositions despite widespread support amongst voters even in the most liberal of states. Violent attacks at universities against non-liberal academics and speakers. I've watched American politics for years. There have never been any olive branches extended by the left. And even when the republicans own congress they somehow have to cede control to the democrat (see Obama years for reference). If one were to criticize Obama for his horrendous Middle East policies or his unwillingness to fire AG Eric Holder, s/he would be called racist, bigot, homophobe etc etc etc. Anyone that is on the "right" has essentially checked out now. Good luck getting them back.

Also, the left is just about as good as one person. How could so many people with disparate views that are often in conflict vote as a unified block with such great ease?
