I'm down for Yang, Bernie, or Warren.
Where I think Yang and Bernie have a disadvantage is that yangs ideas are pretty radical and voters tend to resist change that big when things are going reasonably smoothly. He's solving problems that most Americans haven't acknowledged yet but he's right about the problems existing.
Bernie biggest issue is his name. It's a lot easier to support Warren in suburban America than Bernie. Bernie is a known "socialist" to most Americans and again it's the same issue.
Warren presents her ideas in a way that is relatable to most Americans which is why even though she's not leading she's winning most of the second choice votes. She's acceptable to almost all democrats and to many independent where Bernie won't be.
