> Second, every state covers at least parents, children, and pregnant women under Medicaid (the author of the article would be covered in any state)

I'm unaware of a nation-wide program that covers parents under Medicaid at either 100% or 138% of the FPL.

The numbers I can find paint a different picture, for example, parents in Alabama are only eligible if they make below 13% of the FPL[1].

If you have another source, I'm genuinely interested in it.
