Narrow the field to the real candidates. The massive number of remaining single-digit polling folks should move on to more productive endeavor.
I.e., get out of Bernie's way. Then there is Mayor Pete and the Ukraine question man with his son, Hunter the Gatherer. Both of those candidates are expendable, from the perspective of the peoples' needs and desires. They only resonate with the fat wallet Republican wing of the Democratic Party, and should be sent packing, home, to whatever Joe does, paid speeches or such, and then back to being a small town mayor for Pete.
The contest is Bernie and Warren, one being the candidate to move on to unseating Trump. But clean up the "debate" act by having fewer participants and holding real debates with issue orientation. The single minute soundbite format is entertainment. Not much else. An oral version of Twitter, as to depth of ideas.

And, Amy from Minnesota. Be happy as a Senator. It's your level and you get easily reelected.
