"The American people have given him a mandate?" Pal, that is truly a stretch. 

Through the magic of the electoral collage he was granted a victory. There are 240 million Americans over the age of 18, only 62 Million were conned by Trump. 65 million more didn't buy into the con and voted against him. By the majority of voters he was not given a mandate. 

In terms of the democratic norms he wore down his Republican Candidates with a toxic, abrasive campaign incredible short on facts, full of bluster and long on Bull S--t. 

Democratic norms are to deal in facts, understand and abide by the US Constitution and rulings of an independent judiciary, allow the press to report (Trump controlled messaging) and permit opposition to express their opinion. Lets not even get into his racists attitudes.

Not sure what type of democracy is your ideal, but you are very much off base for the  country that has often gone to war to impose its ideals of democracy on non democratic nations.
