bernie was projected to win because everyone else was dividing up the vote. i expected for bernie at some point to start hitting over 40% support in states if the rest of the vote stayed divided. once it came down to bernie vs biden (and warren/bloomberg) that had to change. no one would had predicted that pete and amy supporters would go to bernie so it makes sense they would boost biden.

i guess the bernie campaign expected the field to stay divided longer and didnt have a plan for them coming together. not sure there was a viable plan available to overcome them uniting.

i think bernies best hope going into super tuesday was a good chunk of voters going to warren instead of biden but that obviously didnt happen.
