In hindsight it's obvious why Trump ran as a republican, but what do you think it might look like if Trump ran as a democrat?

It might seem unfathomable to us today but before the Trump we know from 2016 he considered running as a democrat, supported Hillary, etc. Like I said, now it's obvious why he ran as a republican since lying, fear mongering, being an absolute garbage human being plays very well with them, but what if he did try at running as a democrat?
