Where do I begin? Let's start with "duly elected." A. Lost the popular vote by 3 million. B. Countless verified reports from multiple agencies and the senate about Russian interference, and countless members of his team charged or jailed in relation to it. C. Trump currently doing everything in his power to deter people from voting, and several republicans openly admitting to doing the same. Sound very democratic to you?
As to Germany, maybe some history books will help, at the very least there's always Wikipedia.
