I posted down below about how I'm a registered Democrat and voted Trump. And yes the Democrats are on their way there. There are already some self-proclaimed socialists in office and plenty of others seeking it. Trump is a former Democrat. He does have some left leanings like you mentioned and definitely plays the populist card, but there's no way he could identify with the American left today because theyve become so radical. It's a very small minority of people shifting the party which is a sad thing.

And I'm glad you say Norway isn't a socialist country because a lot of people here think it is for some reason. But, I'd argue Sanders and definitely a lot of his disciples are further left than Norway by quite a bit. And I'm not sure how Bernie is the measurement of how far left the Democrats are considering there's others a lot further down the socialism line than him. He's trying to play keep-up these days.
