John Hickenlooper announced Thursday that he is ending his campaign for the 2020 Democratic nomination. The former Colorado governor had struggled to gain traction in a very crowded field.

Hickenlooper may pivot to take on GOP Sen. Cory Gardner in 2020. He only briefly addressed that in today's announcement video, saying he would give the idea "some serious thought". The Colorado seat represents one of the better Democratic pick-up opportunities in the 2020 Senate election. A recent poll showed him with a 13 point lead over Gardner.

This morning, I’m announcing that I’m no longer running for President. While this campaign didn’t have the outcome we were hoping for, every moment has been worthwhile & I’m thankful to everyone who supported this campaign and our entire team.https://t.co/1ijSjkbzzd
