Colorado leaders have been fretting about how to prepare for the coming “silver tsunami” of baby boomers who retire, require more public services but pay less in the taxes during their working years. But at the state and federal levels, some Coloradans are working to see that older lesbian, gay, bisexual and transgender seniors aren’t left out.

Colorado Sen. Michael Bennet is again trying to pass the LGBT Elder Americans Act, an extension of the Older Americans Act, to classify LGBT seniors as a vulnerable population, as well as ensure the ongoing work of the National Resource Center on LGBT Aging.

Bennet, a Democrat from Denver, tried and failed to pass the legislation in 2015, so he’ll have to pull a legislative rabbit out of his hat to get this one through the current partisan mood on Capitol Hill. Moreover, the campaigns around LGBT healthcare remind the public whats at stake as Republicans try to repeal, replace or gut the Affordable Care Act.

The number of LGBTQ people 65 and older could double by 2030 to 3 million Americans, Bennet’s office said.

“Our laws and research are not current in addressing the unique needs of the aging generation of baby boomers,” the senator said in a statement. “This legislation would provide LGBT seniors, who often face significant barriers to accessing health care, with targeted services and resources. By helping aging service organizations assist older LGBT adults and permanently establishing a National Resource Center, we will better meet the needs of the LGBT community.”

Sen. Tammy Baldwin of Wisconsin, one of Bennet’s four Democratic co-sponsors, said, “Too many LGBT older adults carry the harmful physical and emotional health effects of having lived through a lifetime of discrimination.”

U.S. Rep. Suzanne Bonamici, a Democrat from Oregon, has introduced a companion bill in the House. None of Colorado’s seven House members are among the House bill’s co-sponsors.

“Sen. Bennet continues to champion issues for that matter to LGBTQ Coloradans,” Daniel Ramos, the executive director of Denver-based One Colorado, told Colorado Politics. “The LGBT Older Americans Act upholds the promise to care for our LGBT elders by addressing the unique experiences and barriers they face, so they can age with dignity and respect.”

The state’s largest advocacy organization for LGBT Coloradans and their families is charting the gains under Obamacare.

Its last statewide needs assessment found the uninsured rate among LGBT Coloradans dropped from 15 percent in 2010 to 6 percent last year.

The improvement was the result of expanding Medicaid, so more LGBT people got insurance from the Affordable Care Act.

One Colorado annually release a transgender buyer’s guide for health plans on the Colorado exchange that cover their care.

“There is still a lot of work to do in order to improve the physical, mental and behavioral health disparities between LGBTQ Coloradans and the general public,” One Colorado said its annual needs assessment. “Although insured rates have increased for the LGBTQ community overall, people of color are less likely to have private insurance, more likely to have Medicaid, and twice as likely as white people to have no insurance at all.”
