The GOP has to stop nominating people, who obviously do not like their voters. Jeb Bush doesn't like conservative folks, tea party, anti-amnesty people and people who don't like common core. I'm not voting for people who despise what I believe in. If I wanted to do that, I'd go ahead and vote for Democrats.
In practice, there is no difference between Democrats and e-GOP mainstreamers. So why vote for them.
