a single-payer system, in California. Colorado The Colorado State Health Care System Initiative, Amendment 69, was a citizen-initiated constitutional amendment proposal in November 2016 to vote on a single-payer healthcare system called ColoradoCare. The system would have been funded by a 10% payroll tax split 2:1 between employers and employees. This would have replaced the private health insurance premiums currently paid by employees and companies. It would have begun operating in 2019 and was estimated to require revenue of $38 billion annually (from the Federal government and payroll taxes) and provide coverage for all residents, with no deductibles.

The ballot question passed in all 14 districts that offered the question. Maine In June of 2021 LD 1045 became law without the signature of Governor Janet Mills. The law would establish a board called the Maine Healthcare Board which would be tasked to design, implement, and maintain a state health insurance plan called the Maine Healthcare Plan which would cover all residents of the state of Maine. However, neither the board of the Maine Healthcare Plan have been created because they are contingent on the passage of the federal legislation H.R.3775, the State-Based Universal Health Care Act.
