The big news on Monday this week was that latecomer billionaire presidential candidate Mike Bloomberg had ‘surged’ past Sen. Kamala Harris in a new poll by Hill-HarrisX. By Tuesday the big news was that Harris had departed the race.

Was it Bloomberg’s stellar 6 percent showing that did it? Unlikely. The Harris campaign had had issues, as documented in a recent New York Times piece detailing the deep mismanagement of her campaign.
