The first primary contests of the 2020 Democratic primary race are less than three months away, and the race is quickly heating up.

To help make sense of where all the 2020 candidates stand, Insider has been conducting a recurring SurveyMonkey Audience national poll.

We're mainly interested in using our polling to figure out:

• What percentage of Democratic voters are familiar with each candidate in the first place.
• How Democrats rate each candidate's chances of beating President Donald Trump in the general election.
• If a given candidate were to drop out of the race, who that candidate's supporters would flock to next.

In addition to polling who each candidates' supporters also like, we also asked each Democratic candidate's supporters who they least like over the course of six polls conducted between early September and early November.

You can download all of our polls here, down to the individual respondent data and see the details of the margin of error and sample size for the polls we cite here. (Read more about how the Insider 2020 Democratic primary tracker works).

We both asked each candidate's supporters which other candidates they actively disliked and which of the other candidates they did like. Then we compared those results to the candidates' levels of support among the Democratic primary electorate more broadly.

Overall, Marianne Williamson and Rep. Tulsi Gabbard of Hawaii were the most likely to be heavily disliked among other candidates' supporters, but there were a few other surprising results. Keep reading to learn which candidates each contender's supporters most dislike.
