It’s not R v. D. It is Reformers v. The Combine.
That said, most of the time R > D.
So think tactically.
Don’t make an imaginary best the enemy of a tangible good.
Don’t make an imaginary better the cause of a tangible harm.
Don’t personalize or hold grudges: We don’t just want to change people, we want people to change. Welcome it when it happens.
The long game is make the GOP the reform party.
