But Democrats gave simple explanations: “Joe is the sharpest he has ever been, the economy is the best you experienced your grocery bill increase is in your mind, no need to hold primaries and have your opinion we know this candidate is the best, etc… and if you disagree with any of this your are not smart enough”. I’m harsh but as a non American leaning left economically I found myself in disagreement many times this pas year but any criticism was met with huge suspicion.
Sure, there were many mistakes made by the Democrats' campaign. In your examples, the problem is not that the explanations are simple, but rather that they are obviously wrong.
EDIT: For fun, let's contrast the attitude of each campaign to its detractors. The Democrats say that people who oppose their strategies are dumb. The Republicans say that people who oppose their strategies are Communist pedophiles who want to destroy America.
I don’t disagree, but regarding your edit I’m not saying Republicans are not (way) worse, but that I’m hugely disappointed at Democrats. My hope was that instead of taking inspiration from Republicans they would lead an other way.
Amazing the cognitive dissonance.
Democrats say that people who oppose their strategies are racist, sexist, xenophobic, dumb, fascist, nazi, you name it.
Republicans say that people who oppose their strategies are racist, sexist, xenophobic, dumb, fascist, and nazi.
