I got this in an email from the John Lewis campaign about a survey done to determine who Democrats like for 2020:

Lonnie, we reviewed the results from our recent 2020 Poll and you’ve chosen Beto O’Rourke, Kamala Harris, and Joe Biden as your top 3 choices!

Yes, all the caveats about a sel-selecting poll, but what is a primary anyway, but notice everyone not on the list.
