I just see another old, white, rich (over 2 million net worth) man telling people

So do you have another candidate in mind? All that's left is Warren and she fits all those categories except she's a woman, which doesn't inherently make her better. She is not as far left as Sanders is but her supporters would probably align best under Sanders compared to someone like Biden.

that the last time America elected a far left President, that almost everything was blocked by republicans purely because of politics

Are you talking Obama? He was not far left, the blocking was consistent regardless of the "extremeness" of policies which probably goes to show it was for other reasons.

So if Bernie isn't the best option, that means you have someone else in mind that is the best option. However the only other options are also categorically removed due to your criteria. Who would be a better pick in your mind?
