That's not how it works. There are polls for 2nd choice dude. This isn't hardAnd what would happen if four candidates (Biden, Bloomberg, Buttigieg and Klobuchar) weren't dividing the more moderate/centrist vote? Their polls combine to over 44%, not including Warren, while Bernie is polling at 32%. If Bernie really picks up a good chunk of that moderate support, then okay, he's the nominee. Obviously, that's the question that will determine the nomination.
