It’s NOT about YOU!! It’s about what your constituency wants.
Regardless of what some people see as the downside of Trump (I don’t agree with them anyway) the upside is that Trump makes people her “show their asses” (a more...er...impolite way of saying “show their colors”)
We KNOW what people like Murkowski, Christy, Kinzinger, Cheney, McConnell, Romney, (and a host of others) stand for, in their own words and actions so we don’t have to make educated guesses.
That has great value.
