>>Why don’t liberal appointees ever turn out to be conservative?<<
Leftist Regressives apply litmus tests to their nominees, Republicans don’t.
It’s long past time for the ‘Pubs to wake up and do the same. Otherwise, we’ll get more phonies such as Stevens, Kennedy, Roberts, and Kavanaugh. Scalia and Thomas are the standards.
President Trump has appointed more than sixty Federalist Society members... ;-)
I think it’s too soon to know for sure whether Kavanaugh is a phony. But I am wary.
