It's way beyond GOP dead.
GOP has been dead for decades.
Ever notice they never stood for anything they campaigned on? Ever notice the canidates that would have done something never won the election? Ever notice that the dual party system has been and would always be an illusion.
The illusion is gone. There isn't any need for it anymore. Your vote hasn't mattered for decades and, while we may yet go through the motions of an election, the results will still be scripted and planned long before any vote is cast. The evil ones are in power and good hasn't stood for anything to stop them. The illusion of freedom we have enjoyed is over as of now. This is reality until good finds enough balls to fight evil.
