Well, it's obvious from your posts that Dems learnt nothing from the time of his first victory, and maybe you, too, missed the tested and proven fact that Trump chronically underpolls. Those who support him often consider their position disfavoured by pollsters and thus keep it in secrecy till elections.

I predicted such an outcome already in October, though, to be honest, the ship had sailed for Dems as early as after the abysmal June debates and the "Butlerian Jihad" incident on July 13.

Moreover, you must understand that Trumpism is only a symptom of your (Americans’) deepest societal crisis since the Great Depression; the Dem Party, especially neocon wing, proudly shares their part of responsiblity for this, and for erosion of the American Republic on its path of (failed) transition according to geopolitical reality of the day.
