I completely agree with Carlin's bit about politicians and how it's not the politicians who suck but "the public sucks."
In fact we see a perfectly good example of that pearl of wisdom going on in the Democratic nomination race right now, the public is picking Joe Biden. Seriously guys, Joe Biden?
"Moderate" Democrats had an enormous list of candidates to choose from and they picked literally the worst candidate out of all of them.
The public say they want change yet they vote in the same establishment politicians into office over and over again who take money from big donors and then the public whines about how nothing changes. The voters are their own worst enemy.
Individual people can be smart, but groups of people are dumb as a rock.
