Some Democrats are further left than a few of the further right Republicans, but not many by my observation. And zero Democrats are as far left as Trump is far right fascist. Trump doesn't know jack sh!t about the Constitution because he has no respect for the Constitution nor the rule of law. He wants, and looks like he has, a Cabinet and administration that is absolutely loyal to him over and above any loyalty they may have ever had for the Constitution or the rule of law. The U.S. has entered a phase where the only law is whatever Trump's says it is under his current whim, which is subject to change at any time. Trump has implemented several actions that fall under the label of fascism. No Democrat or any Republican has ever done so. Opposing Trump is the only option open to an American opposed to a fascist takeover of the U.S.
