Some Republicans say that guns aren't the problem, the problem is mental health. Maybe that could be turned into an argument for universal access to healthcare. Possibly an argument for single payer.
Ironically, Republicans are not likely to embrace that logic, however.
Today I hear in the news that quite a few people will loose access to healthcare as the pandemic emergency winds down. Some low income folks, in states like Texas, will loose access to Medicaid expansion; states that still refuse Obamacare's Medicaid expansion.
Others, even in states like Washington that has the Medicaid expansion, will likely get confused by the myriad of choices and miss open enrollment periods as some people need to reenroll in various plans as things change after the pandemic.
In some cases, folks will fall through the cracks and loose access to psychiatric medicines that they need as the complex landscape of healthcare finance keeps changing.
Add to this more and more guns in society and you have a recipe for problems.
