South Florida’s Wayne Messam appears in presidential poll. But almost nobody knows who he is.

Of the 23 Democratic presidential candidates, Messam had the largest percentage of people who didn’t know about him. He wasn’t far worse than some of the others, including Montana Gov. Steve Bullock who entered the race on May 14 (83% hadn’t heard enough about him to have an opinion), spiritual author Marianne Williamson (83%) and U.S. Rep. Seth Moulton of Massachusetts (84 %).
