Montana Governor Steve Bullock became the latest Democrat to end his presidential campaign on December 2, acknowledging in a statement that he “won’t be able to break through to the top tier of this still-crowded field of candidates.”

Like several others who have dropped out of the race, Bullock had a wealth of experience and was solid on many key issues for Democrats. He repeatedly vetoed abortion restrictions passed by the Republican-controlled legislature, yet somehow persuaded the majority party to expand Medicaid in Montana and take steps to limit the influence of dark money. He could have given President Donald Trump a hell of fight in a general election, having won re-election in 2016 even as Trump carried his state by 20 points.
