I think the bigger thing is that a significant percentage of the population is more concerned with fitting in with their tribe than they are with thinking critically. Furthmore, a good percentage of those people are only minimally capable of thinking critically about a situation. Those people have the same vote I do. Well, not exactly. I live in a so called purple state of divided government, aka a swing state. Still, on the state level the percentages are similar. When people are able to blatantly lie and transmit that lie over and over with effective anonymity to influence the easily influence with zero negative consequences we get the government we have today.
We get a government which no longer represents the people, but instead enacts laws and polices favoring those who give them the most money. The saddest thing is that the voting public is entirely capable of putting an end to it. Well....we would be if so many of us were not so selfish, apathetic, gullible, and/or just down right dumb. It is no coincidence public education is attacked by the republicans. However, the democrats don't do themselves any favors with how the public school systems are run in our biggest cities either.
