Not really, I mean Bernie Sanders is not a Socialist since he doesn't want to nationalize any industries which is really the sine qua non of socialism. He is a Social Democrat. Actual socialists usually identify as Leftists instead of Liberals.
And if Bernie were Emperor for a while, he'd nationalize a few industries, surely. I can barely imagine would Trump would do if he could just make up the law as well.
As an example, do you think that, given the ability to enact whatever legal changes he wanted, Bernie Sanders would nationalize our telecommunications infrastructure? Or our health care system?
I don't have any specific, citable reason to think he would, but I think there's plenty of reason to believe they're things he might want to do.
There's barely a hard line between Democratic Socialism and Social Democrats.
