Former Colorado Gov. John Hickenlooper ended his long-shot campaign for the Democratic nomination for president Thursday — but left the door open for a possible Senate run.

“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,” Hickenlooper wrote on Twitter.

He elaborated in a video statement in which he said he’d give “serious thought” to a run for the US Senate.

“People want to know what comes next for me. I’ve heard from so many Coloradans who want me to run for the United States Senate. They remind me how much is at stake for our country.

“And our state. I intend to give that some serious thought,” he said.

The ex-governor’s departure follows pressure from national Democrats to abandon his campaign so he can challenge Sen. Cory Gardner, a Yuma Republican whose seat is considered vulnerable in the GOP-controlled Senate.
