Montana Gov. Steve Bullock said Monday that he is ending his bid for the 2020 Democratic nomination. Bullock made the announcement on Facebook, linking to a longer statement on Medium. He said that "it has become clear that in this moment, I won’t be able to break through to the top tier of this still-crowded field of candidates."

Bullock is in his 2nd term as governor of Montana, a deep red state that voted for Donald Trump by a 58-33 margin over Hillary Clinton in 2016. It has voted only twice for a Democratic presidential nominee since 1950. Bullock frequently used the talking point that he was the only Democrat in the field that won a Trump state. However, it wasn't enough to help him break out in this historically large field.  His national polling average was well under 1% at the time of withdrawal.

The Democratic field is now at 16, still massive by historical standards. The last several weeks has seen three lagging candidates leave the race. In addition to Bullock, former Rep. Joe Sestak departed Sunday and Miramar, Florida mayor Wayne Messam suspended his campaign on November 20.  However, this winnowing has been largely offset by two new entrants: Former New York City mayor Michael Bloomberg and former Massachusetts Gov. Deval Patrick.
