GOP Strategy

Can someone help me understand what it is? In the short span of a couple of weeks GOP mouthpieces and operatives have done, what looks like, everything humanly possible to alienate 1. the largest block of actual voters- women and 2. the single largest growing voting block- Hispanics. If sexism and racism is a core plank of the GOP platform can they ever regain a majority? Is the real issue within the GOP that they can't control Rush-Newt-Steele-Cheney or that they don't want to?
