I have no idea where you're going with the last 40-50 years comment. I honestly don't.
Complaining about a flaw in one political party and giving the other party a pass when the flaw is universal is a bad take. I encourage people to shake off the blind loyalty and hold leaders of their own party to the same standard they'd hold leaders of the other. Don't just assume your favored party isn't doing the same underhanded and irresponsible stuff simply because they're your party.
