Most on my side literally cannot understand how these polls could be true. But I believe that we must accept them, and then, as citizens, we need to reckon this radical disconnect between us. How can one side be so certain, and the other side so certain in the opposite way?
The answer to the question doesn’t have anything to do with Trump, really. At least not for me.
I belong to the faction (I think that ‘tribe” is a crappy word for it) who believes that IN GENERAL, that the average citizen is better off if the federal government is not running around trying to “solve problems”, that free enterprise and self-determination do a better job of solving those problems over time, and where solutions are needed, letting local governments address them is wiser than trying to impose centralized, one-size-fits-all solutions from the central government.
Admittedly, what I just described is not even a majority view among Republican voters, but it is indeed my view.
THUS, I would show up on the “support” side of your aforementioned poll NOT because I believe Trump supports my views as stated, and NOT because the GOP supports my views as stated, but because they together represent a closer match to my views than anyone on the Democrat side of the ledger.
Hope that helps.
