Although it’s been implicitly stated by other posters in this thread, welcome to the club.
I started a similar thread about this topic nine years ago and the situation has only gotten worse. Back then, I attributed the problem to the extensive amount of time and money needed to run for office. That’s still a big factor, but now there’s a greater impulse to dispose of any inclination to think rationally about issues. That’s why you have so many politicians rallying around dubious causes and espousing conspiracy theories that not too long ago would’ve landed them in mental institutions or at least resulted in having guardians ad litem appointed to handle their affairs.
