Montana Gov. Steve Bullock said Tuesday that he will seek the Democratic Party nomination in 2020.  He joins a historically large field seeking to unseat President Donald Trump. Bullock released a video making his announcement. 

Bullock is likely to be one of the final notable entrants in a Democratic field that now numbers 23. That list is below, ordered by the current national polling average.  18 of these candidates have qualified for the first two debates in June and July. The field is capped at 20 (candidates will be split randomly across two nights). If more than 20 become eligible, a tiebreaker process will be used.
