The Democratic field is large, it's early in the game, and most voters are still undecided, so it's currently almost impossible to predict who will win the nomination. Sanders is the predicted front-runner (although Joe Biden could knock him off if, or when, he enters the race), but he also has more name recognition than most of the candidates, so this could very well change as voters get to know the others. And don't discount the fact that women are expected to make up about 60% of the Democratic primary vote. If the 2018 midterms are any indication , there is a ton of enthusiasm around electing someone who represents their values and is a woman.
