AR - I see. Your core point is that Biden has been wrong on issue after issue and Kuchinch has proven to be right on big issues that at the time were not popular..

I totally get it and wont argue your point.

Given that the US has a Representative Democracy being 'right" on an issue does not really matter if you cant win office. And winning office many times requires that politicians are WRONG on issues.

Here is where i think you might consider looking at Political leaders from a different lense.

Obama said and stood for policy issues much more in line with my "liberal" policy beliefs. He too was opposed to the Iraq war. He campaigned on Universal Health Care.

But none of that changes the fact that Bidens American Rescue plan and if passed his infrastructure Bill will have far more positive effect on the lives of poor and middle class Americans than anything passed by Clinton, Bush2, Obama or Trump...

So sure it is great if a leader "gets it right". And certainly Kucinich has don that. I will argue Sanders and Warren did as well but we can table that for another day. But it is BIDEN that won and BIDEN that is getting the Bills passed. Not Kusinich not Sanders not Obama.

This is how Republican Democracy works.
