Trying to “Fix” the GOP is the Definition of Insanity
The premise of the article is actually pretty silly. A political party isn't a machine that can be "fixed," it's a collection of people who share some general political tendencies.
What Rucker really means by "fix the GOP" is actually, "make the GOP act the way
he wants it to act."
What it would take to "fix" a political party in the sense Rucker seems to mean it, is either to kick out all the ones who you don't like; or to convince the people in the party of the correctness of your ideas.
The latter is obviously not an option: it requires hard work and, worse, it requires people to have a clue about what they stand for and why. Much better to wail and gnash teeth, as Rucker is doing here. And, of course, either to eject the apostates or start their own party.
As to starting one's own party -- again, that requires hard work and a clue -- and so the likes of Rucker will continue to wail and gnash teeth.
