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.
