But in a partisan era in which many Democrats are seething with anger toward President Donald Trump, messages about compromise and compassion from Hickenlooper and some of his rivals have largely fallen on deaf ears.
Hickenlooper's bid failed to generate serious traction in a crowded Democratic field. The majority-red Senate is now comprised of 53 Republicans and 47 Democrats, with the former defending the top ten most contested seats heading into the election. Cory Gardner in 2020.
Mr Hickenlooper is the third candidate to withdraw from the Democratic race. A July poll of likely Colorado voters from a Republican-aligned firm found Mr. Trump with a 39 percent approval rating in the state and concluded he trails a generic Democratic general election opponent by 12 percentage points. Curtis Hubbard, a Democratic strategist for a firm that has worked for Hickenlooper in the past, has recently registered domain names like Hick4Senate.com in the hope that the former governor switches races.
One Colorado Democrat said Hickenlooper will spend time now preparing for a possible Senate campaign, with a focus on a fundraising network and an organization while building as much anticipation as possible.
"[Coloradans] remind me what's at stake for our country, and our state", he said in the video. "I think there might be a kind of a new silent majority", he said, "of people that are also going to want to see achievement".
Hickenlooper said he would but added, "How come we're not asking, more often, the women, 'Would you be willing to put a man on the ticket?'" He did not make an announcement on that decision in the Thursday video, but acknowledged the possibility.
John Hickenlooper announced he is dropping out of the Democratic presidential primary on Thursday via Twitter. "I think that perspective of trying to speak up for the disenfranchised, speak up for the people that tend to be marginalized, I think that's admirable", Hickenlooper explained.
He said he had been approached by Coloradans to run for the Senate. By rejecting a Senate run in their highly contested states, Beto O'Rourke, John Hickenlooper and Steve Bullock may be doing their party a disfavor.
Hickenlooper governed as a business-friendly Democrat in Colorado while advocating for some progressive policies.
And though it's still unclear whether he will run for Senate, should he decide to do so, he will have to face an already-crowded pool of at least 11 others, including several high-profile candidates who have already raised more than $1 million apiece, including former state senator and gubernatorial candidate Mike Johnston and former House Speaker Andrew Romanoff.
The push to recruit Democrats to run for the Senate took another blow this week when Stacey Abrams, whose national profile rose a year ago when she narrowly lost a gubernatorial bid in Georgia, announced she would not run for the seat held by Republican Sen.
Democratic presidential candidate former Rep. Beto O'Rourke of Texas relaunches his campaign from his hometown of El Paso after a mass shooting that killed almost two dozen people there. Hickenlooper responded by saying he was not interested in running for Senate, something that mirrors what he said in February when he said he wasn't "cut out" to be a Senator.
In that same interview, Hickenlooper acknowledged that it will be hard to garner the media's attention due to the crowded field of candidates.
He follows California Congressman Eric Swalwell, who ended his short-lived bid in early July, leaving twenty-three candidates still seeking the nomination. The former mayor of Denver chided Medicare for All as an ineffective way to achieve universal healthcare and championed his track record of getting things done as governor of a purple state.
