If polling is to be believed, Joe Biden is now far and away the frontrunner for the 2020 Democratic nomination. The question is whether that can last now that the target is squarely on his back.
There is a clear appetite among some Democrats to coalesce around Biden and avoid a food fight. But there is also rising animus toward Biden on the left, and no hesitation from Bernie Sanders and Elizabeth Warren to take him on.
If they draw blood, we're going to have a messier scrum. And with 20 candidates all vying for the top spot, things could get out of control. Thats because a large field breeds chaos and uncertainty.
