Probably the only part of Obamacare worth anything was its expansion of Medicaid.
Medicaid expansion saves lives, and saves people from financial ruin.

Uninsured patients who have these emergency procedures are almost always left with a catastrophic financial burden, Albright said. This occurs much more frequently for uninsured patients in states that decided not to expand Medicaid coverage, according to Albright and his colleagues from Duke and Memorial Sloan Kettering Cancer Center in New York.

They also found that these catastrophically expensive emergency surgeries often could have been avoided, if the patient had had access to preventive health care services.

His calculations found that adoption of Medicaid expansion in the 12 holdout states would have prevented 50,000 incidences of catastrophic financial burden resulting from uninsured surgery in 2019 alone

So why have those 12 states refused Medicaid expansion? Because they've got to own the libs, donchakno.
Sure, someone will always claim that its because the people of those states don't want that "socialism", but ballot measures have proven that to be a lie.

Six red states have expanded Medicaid eligibility by ballot initiative so far: Maine in 2017, Idaho, Nebraska and Utah in 2018, and Oklahoma and Missouri in 2020.

Missouri is a good example.
Last year voters in Missouri approved Medicaid expansion. Missouri’s legislature refused to include funds for the expansion in the state budget, and Gov. Mike Parson declined to implement the unfunded program.
It required the Missouri state Supreme Court to order the legislature to do their jobs.
Around 830,000 people have gained Medicaid coverage as a result of ballot initiatives.

Of the remaining 12 states, only three of them allow ballot measures that voters can force their state governments to represent them: Florida, Mississippi, and South Dakota.
In Florida, the Legislature made changes to the ballot initiative process that drove up the cost of collecting signatures and raised the number of signatures needed, in direct response to an effort to put Medicaid expansion on the 2020 ballot.
This derailed the effort, and it will have to be started again from scratch.

South Dakota will likely be voting on Medicaid expansion in 2022.
An effort for Medicaid expansion in Mississippi has just started.

The end of the pandemic, which should be happening shortly, will ironically have a very negative impact on Medicaid enrollment.

A new report showed that about 15 million Americans who enrolled in Medicaid during the public health emergency could lose coverage when the emergency declaration ends.

Those at risk for losing coverage include almost 9 million adults and 6 million children, according to the analysis published by the Urban Institute with support from the Robert Wood Johnson Foundation.
