1) Bernie - been this way since the last campaign. Don't agree with him on everything, but he seems the most progressive and has proven it with the most consistent voting record over the past three decades.
2) Warren - I think she'll do a lot of good, but not as progressive as Bernie or as consistent. Really though, if Bernie is like an 8.5/10, Warren is like a 7.8. I would be happy with either one, and there are issues that Warren is ahead of Bernie on for sure:

Bernie has obviously changed his tune on guns but this is another level and I agree with pretty much all of it.
The rest are mostly the same old corporate dems to me, with some being a little more progressive on this issue or that one. Don't really care to distinguish between them, so I'll say Yang gets the last spot on the podium for standing out with UBI and because at least he won't say he'll take Trump behind the high school and give it to him.
But the first two are way ahead of the rest to me.
