As much as I want that to be true I feel like the GOP is an unkillable beast that will be dragged kicking and screaming into modern times. It'll adapt to our message, but never embrace it. It'll simply keep coopting any dissident movement, just like the Democrats do (Civil Rights, Anti-War, etc.). You pretend to be their allies get them into your fold and then the constituents stop caring that you don't follow through or only half address the issue, because the other guys are worse.
I want to see the GOP disappear, but I don't share the optimism of the author.
