Loser Politics is the psychology of the right wing — the mentality of Confederates through the ages. It is the also rans, the disaffected former military or government personnel, the failed actors and artists, closet gays, and all those jealous jerks who are butthurt over their own assorted failures.
It is the mindset of the Lost Cause religion. It’s the Libertarian 1% who spend 80% of their money to capture 45% of the government which is enough to achieve minority rule. Loser Politics is the Republican Party, capable only of performative governing and not actual governing.
