For one, propaganda is a hell of a drug. Fox two minutes hate “news” will tell anyone who listens that every single problem you have is the fault of Goldstein liberals/leftists/Democrats.
A point for Trump is that “conservatives” are also completely jaded and cynical about the system as well as we are, their chosen method is to use Trump to burn it all to the ground and “start new” with their “strong man” who will force the change they want to see. They see Biden as a feckless, weak, liberal who not only can’t fix the issues we have, but won’t do it because he’s in x,y,z persons pocket (completely ignoring that Trump doesn’t need to have someone to serve as he’s serving himself.)
I think we’re all fed up with the system, but the neoliberal greed is good 80s assholes will continue the beatings until morale is improved.
