This is kind of confusing to me. What would make a left-leaning voter want to vote for Donald Trump? After he has:
-Gone on record saying he thinks global warming is a myth, and intends to eliminate a good deal of environmental regulations. Trump intends to withdraw from the Paris Climate Agreement, and has just appointed Myron Ebell (a notorious climate denier) to serve as president of the EPA's transition team. Seems ironic for someone who normally aligns with the green party to switch to a candidate who will actively oppose environmental efforts.
-Trump has no political, legal, or military background. Even his actual business background is on very tenuous grounds. Donald Trump has had many failed business endeavors, often leaving his investors on the hook for hundreds of millions of dollars in debt, while he skirts away scot-free. Trump has bankrupted four companies, yet still managed to game the bankruptcy laws to his advantage-- a fact that he now publicly brags about.
-Trump is going to appoint ultra-conservative justices to the Supreme Court. That's should be a glaring red flag for left-leaning voters, because by nature it will be in direct contention with a large number of their beliefs.
-Trump has consistently given validation and cabinet position to the Republican party, and worse yet, the rising alt-right culture (which is generally said to be a thin veiling for white nationalism). Steve Bannon, the white-nationalist editor of Breitbart (a cesspool of art-right propaganda), is now a high ranking executive in his cabinet.
-"Grab her by the pussy", shadiness surrounding his Miss America pageants, Trump's growing body of sexual assault allegations, etc. I don't know why female voters are so willing to look past this.
In short, I'm not really sure why leftist voters would consider him a good choice. Maybe they could come to view him as the lesser evil, when compared to Hillary Clinton, but I'm still somewhat doubtful of how often this is the case.
Could you maybe explain a bit more about what exactly you like about Donald Trump? (Preferably relating to policy, but not exclusively.)
