Many have pointed out that Trump did not choose the defense that stood the best chance of working: "Some of this happened, but the way that it happened was not technically illegal." opting rather for the near impossible "Nothing they say is true, it's all lies. I'm innocent."
This is only a confusing choice if you miss the real way that Trump himself views this case. It's not illegitimate because he "didn't do it" it's illegitimate because he's too important of a person to be charged. 1/
