In fairness, these same points were made prior to Trump winning the first time. And we all know how that turned out. Assumptions are dangerous. It's important, IMO, to approach this with a more concrete strategy for winning. We still elect the President with the electoral college, whomever whens the Democratic nomination better be able to hold the blue states and flip a few midwestern/rust-belt states. So then you ask yourself....what appeal accomplishes that? Too early to say at this point probably, but that's how you win.
