He's a lot better than any realistic alternative. He is way better than the average yank politician. Even if he succeeded halfways with just one of his policies he will have made a huge material difference for millions of people. He demonstrates how "socialism" is no longer a scary word but something that can be immensely popular.

He can still be absolute dogshit despite all of the above being true, the bar is that low in the post-fascist consensus of late capitalism. I know that he is not the new Lenin. I remain modestly optimist about him being a net giid but I will not be disappointed or surprised once he does what every other social democrat has always done.
