Trump is not of the Left. In fact, he was nothing like this till he joined the Right as a member of the Republican Party. He left the Reform Party at the urging of Jesse Ventura because of Pat Buchanan being Far Reich.
Billion dollar lawsuits for newspapers and television stories not to his liking (even a poll by a little old lady and some small obscure Midwestern newspaper), getting shows canceled (Colbert, Stern), having what people say on television shows on TV get limited (literally live on air by the a show producer as seen multiple times on The View), threatening to pull the FCC licenses of television channels (ABC, NBC, CNN), removal of from everything from the Pentagon to the Smithsonian to Parks Department references to Harriet Tubman to the Tuskegee airmen to Native Americans, etc, attempting and threatening to take legal action against what he views as political political foes, including some who have worked for him (Bolton, Obama, Clinton...)..... those are hardly actions of the Left. Those are Far Reich Fascist.
