DENVER | Colorado lawmakers have delivered many of Gov. Jared Polis’ first-term priorities, but minority Republicans also claimed some victories by the last day of the session, especially in slowing down or killing legislation they considered overreach by majority Democrats.

Colorado lawmakers adjourned the 2019 legislative session Friday evening after passing bills on health care, sex education and sports gambling.

Polis says he is “thrilled” with majority Democrats’ accomplishments during the four-month session. He thanked Republicans for collaborating on two of his priorities: health care and education.

Lawmakers passed an opt-in sex education bill augmenting instruction on sexual orientation, consent, pregnancy outcomes and sexually transmitted diseases.

And they passed a bill to ask voters in November to legalize online and in-person sports gambling in Colorado.

Polis says he’ll sign those bills.

At the start of the year, Polis pledged to stabilize fragile and costly health markets, push renewable energy, establish state-funded full-day kindergarten and grant more local control over how and where Colorado’s $32 billion oil and gas industry can drill.

By the final day of the four-month session, lawmakers had delivered on those promises.

“We want you to pay less for health care because you are getting ripped off,” the Democratic governor said, flanked in his office by white billboards listing his health care and education achievements. “Americans are getting ripped off on health care every day.”

Lawmakers passed an ambitious proposal to create a state reinsurance program designed to lower health insurance premiums on the “Obamacare” individual market by up to 35% in rural areas and an average 21% across Colorado.

If approved by Washington, the initiative could have an immediate effect on the 251,000 residents who buy health coverage on the individual market set up under former President Barack Obama’s health care law. Reinsurance allows insurers to lower premiums by having the state take on their highest-cost cases.

Polis said he hoped that President Donald Trump’s administration will look favorably at the initiative. He said he was consulting with Florida Gov. Ron DeSantis, a Republican who plans to submit a similar request.

“What helps is that we have a blue state and a red state going in with very similar requests,” Polis said.

Colorado lawmakers also passed legislation to seek federal permission to import cheaper prescription drugs from Canada. Vermont led the way by enacting a 2018 law but has yet to ask Washington for approval.

The U.S. pharmaceutical industry fought the measure, arguing the safety and quality of prescription imports cannot be guaranteed.

Colorado adopted a hospital price transparency law earlier this session. Another measure is designed to protect consumers from surprise out-of-network medical bills in emergencies.

Also on the governor’s desk is an ambitious climate change measure calling for a drastic reduction in greenhouse gas emissions by 2050. That complements a new law emphasizing safety and local control over production in oil and gas regulations. Republicans fought both measures.

GOP Sen. Jerry Sonnenberg said this year, his 13th in the Legislature, was the most acrimonious. He insisted that Republicans were compelled to resort to filibustering and other methods to force the new Senate Democratic majority to slow down, seek compromise or fail.

“It didn’t always work,” he said.

At the top of Polis’ January wish list was full-day kindergarten, and lawmakers overwhelmingly endorsed it. Polis, an education and technology entrepreneur, stressed in his campaign the importance of early childhood education in providing students, especially the disadvantaged, a step up in their school and career prospects.

Democrats also delivered hotly contested victories in enacting a “red flag” gun law designed to remove firearms from people who pose a threat and adding Colorado to the National Popular Vote movement, in which states agree to award their electoral votes to the presidential candidate that wins the nation’s popular vote.

They’re also asking voters in November if the state can permanently keep excess tax revenue that otherwise would be refunded to residents.

Not all the governor’s efforts succeeded.

A Polis proposal to ask voters to raise taxes on tobacco and nicotine vaping devices was defeated. So, too, was legislation to create a $1 billion state-paid family leave program for all Colorado workers. A death penalty repeal failed, as did a measure tightening rules for vaccination exemptions for children.

Lawmakers did endorse a bipartisan bill to ask voters to legalize online and on-site sports betting. If approved, Colorado would launch a limited betting market that would generate roughly $10 million for a state water conservation plan and health programs.
