Usually you contact their campaign office. A lot of times if you make a donation they'll ask if you want a sign. But they'll give you one for nothing as well.
Up until now I've mostly seen the " Any Functioning Adult 2020" signs.

All of a sudden there were more presidential signs I noticed as I drove around town today. I saw my very first Pete sign which made me happy. Also saw Bernie,Warren and Mike.This was just a few streets. Should take time and make a survey. Someone please let us know where these signs are distributed.
