Those who spend their days, nights and weekends talking Colorado politics are talking more and more about the future of Kerry Donovan.

And now Donovan is talking more about Elizabeth Warren.

The influential state senator from Vail is seen as a future candidate for higher office, very likely the U.S. Senate, as a possible successor to another presidential candidate, Michael Bennet, if Bennet winds up in a presidential administration or trades his passion for policy for some other kind of public service before he faces re-election in Colorado in 2022.

On Monday Warren’s campaign announced that Donovan is endorsing the liberal senator from Massachusetts for the White House, not the longshot U.S. senator from Colorado.

Donovan also is snubbing Vermont Sen. Bernie Sanders, a darling of her party’s political far left who handily beat Hillary Clinton here in the 2016 caucus.

Both decisions could weigh on the trajectory of Donovan’s political future.

She represents on of the legislators most rural districts, as it is, one that’s seen an exodus of mining jobs for a long time, and Warren is one of the leading opponents against fracking.

Statehouse Democrats have opposed fossil fuels, but if the economy sours and Colorado voters blame Democrats, the association could prove troublesome in a general election.

Donovan is the first big-name Colorado politico to come out in favor of Warren.

The campaign noted Donovan’s endorsement advances a series of Warren events in Colorado this week — Tuesday in Pueblo and Colorado Springs, Wednesday in Aurora and Denver, and Thursday in Boulder and Fort Collins.

Donovan was seen as a potential U.S. Senate or U.S. House candidate this year, before opting to stay in the legislature, where she was a key figure in the Democrats’ new majority in the state Senate.

She has carried high-profile health care and rural Colorado legislation, in addition to being the mother of the nation’s first statewide Public Lands Day.

“Elizabeth Warren is a champion for working families with a vision for big, structural change that will level the playing field for all Coloradans,” Donovan said in a statement released by Warren’s campaign.

“Her plans will help boost the economy of rural Colorado, invest in rural broadband, and make sure no family goes bankrupt because of the high cost of health care and prescription drugs. I’m inspired by her decision to not have high-dollar fundraisers, which means she can spend time meeting and listening to voters, instead of big donors. She’s not afraid to stand up to powerful special interests, and fight to build an America that works for everyone. I’m thrilled to join this grassroots movement and be in this fight with her.”

Warren on Monday called Donovan “a fierce advocate for all Coloradans who has worked tirelessly to protect our public lands, bridge the rural-digital divide, and level the playing field for working families.”

Warren has rolled out an aggressive plan to reboot the nation’s farm economy with a slant from the left. She also is a backer of the Green New Deal.

Colorado Republicans found Donovan, a cattle rancher, and odd fit with Warren, nonetheless.

“Elizabeth Warren’s Green New Deal would be devastating for the Western Slope, but Kerry Donovan doesn’t seem to care,” Kyle Kohli, a spokesman for the Republican National Committee in Colorado, said in an email to reporters.

“From banning fracking, to eliminating countless energy jobs, to introducing crushing new taxes on farmers, Warren’s Green New Deal is a recipe for economic catastrophe in rural Colorado.”
