I appreciate your passion and concern about the importance of universal health care. The problem, since Theodore Roosevelt supported the goal over a century ago, is that it has been perceived as "Socialist" or "Communist."
The European states such as Germany who introduced universal care during the Progressive Era did so as a way of maintaining "conservative" control over the country.
In the 1920s, after the second red scare and Russian revolution, American business leaders offered "welfare capitalism" including health care, pensions, and vacations, in order to stave off the "socialist menace."
Since then the Democratic strategy has been to slowly and painstakingly construct a social welfare safety net that will meet the constitutional constraints and political realities of the United States.
FDR wanted health care included in Social Security but couldn't get it done. Harry Truman fought for expanded health care and was rewarded when Lyndon Johnson signed Medicare into law with Truman and gave him the first card. Likewise Medicaid provided health care to the poor.
During the Clinton administration the Children's Health Insurance Program expanded health care for poor children.
Obamacare was the next building block in this edifice. It was seen as a betrayal by the left who demanded universal coverage, but it dramatically expanded access to healthcare, especially in states that accepted the medicaid expansion.
Most opposition to Obamacare has come from older rural whites who have seen it as a transfer of wealth and care to younger and poorer minorities.
If we can't convince people to wear masks to stop a global pandemic how do we convince them to fund universal health care?
The insurance industry also has a vested interest in maintaining their line of work and ability to pay their employees and stockholders.
The great debate between the "moderates" and "progressives" has been about how to achieve the goal of universal coverage. Most recent polling has suggested that "Bernie Democratic Socialists" don't make up more than 24% of the American people. It is very hard to achieve your desired change when you make up only about a quarter of the population.
When the number of Democrats in the House expanded in 2008 and 2018 it made the Democratic party more diverse and more conservative. The remaining Republicans became more reactionary and dedicated to opposing "leftist" initiatives than ever before.
If only Mitt Romney voted to remove Donald Trump from office and the Republicans have stacked the courts with conservatives then there is a lot of work to be done to heal the country and our democracy.
The federal bureaucracy needs to be restaffed and needs to heal. Civil discourse needs to be restored. Justice needs to be meted out for criminal behavior and racial hatreds and crimes. The country needs to recover from Covid-19 and the political wars of the past five decades. The economy needs to recover and be made much more equitable. An effective strategy for combating and adjusting to Climate Change has to be implemented. Race relations need healing. International relations need to be restored. The epidemic of gun violence and youth depression needs to be forcefully addressed. Our schools need to be fully funded so that ALL children have access to a first rate education.
Each of these tasks are massive and will require the efforts of people from all walks of life including economic and social conservatives.
At one point in his presidency Obama told the activists to "make" him do the right thing. I think what he meant is that the activists need to create the groundswell of public support to provide political cover. Progressives need to campagn for local and state level offices across the country and build a massive intersectional movement demanding universal health care.
Then president Biden, or Harris, or Cuomo, or whomever will sign it into law. But it will not happen immediately.
Now if we can just save the post office.
