Yes, because supporting the POTUS, no matter who, is now a bad idea?
There is a difference between showing support and blindly following a person no matter his flaws. The GOP should learn that. If Trump runs again, Biden will get my vote. If someone sane who represents me runs (fiscally responsible, not an asshat, not trying to enrich himself and family, not trying to take away gay rights or abortion, understands foreign policy and the impacts it has domestically, not trying to make themselves Putin, amongst others) is the GOP candidate ill gladly punch that ticket.
I dont have much faith in voting R.
