My state has so far refused to expand Medicaid and I don't see it happening any time soon. It's a shame because we have a 9% uninsured rate and that has relatively flat for quite some time.
To me it's not really a political issue, but it politics unfortunately dominates the discussion surrounding the issue. People that can't afford health insurance forgo preventative coverage (for no fault of their own) and only get help when the absolutely need to, costing them and, in effect, the rest of us, much more in the long run.
It's hard for a lot of us to admit it, but providing coverage to everyone (not necessarily arguing for single-payer, but just guaranteed basic coverage) is far cheaper than the status quo.
