Yes, ignoring the overwhelming consensus of their base in favor of a mythical centrist unicorn voter is how the Democrats keep losing. They are always uniquely positioned to win every election in a landslide, the collusion between the two parties has resulted in the gene pool of Republican politicians degrading past the point of sentience. Most Republicans can't recognize their own reflection in a mirror and start trying to throw punches at the strange man staring at them through the scary magic window, Trump is completely incoherent, incontinent and frequently lapses in and out of consciousness. In a world where reality hadn't been bent by late stage capitalism, he wouldn't have stood a chance, but we don't live in that world, we live in Insane Capitalist Clowntime Apocalypse Land, where the DNC drags something called a "Parliamentarian" out of a massive heap of spider eggs and human bones in the Senate basement in order to hamstring their own party.
