I'll say what I said 4 years ago, at the end of the day whoever's high-minded rhetoric, idealistic policy, and feel-good signaling you prefer is going to get confronted with the same set of congressional, institutional, and judiciary constraints that are going to box in and limit the realistic range of movement anyone occupying the executive is going to have. To the point that functionally a Bernie or Beto or Yang presidency is likely not going to look all that dissimilar in practice compared to the framing people give into in primary season.
There is certainly enough notable deviation that can come from prioritization, crisis decision-making, appointments, and focus to warrant pulling for who you prefer, but at the end of the day McConnell is not going to be persuaded to give everyone $1000 by a Yang meme or let any of his caucus get behind a Green New Deal, liberals aren't going to allow Beto to go too moderate, moderate Dems aren't going to allow anyone to go too left, foreign policy is not going to drastically shift, and even the most progressive appointments are going to come face to face with institutional inertia and court challenges that will bog them down and limit their allowable scope.
