Right. First off, they're expanding Medicaid, not Medicare. Medicare is for old folks. Medicaid is for poor people. However, I digress.
You do realize that the states bear a significant burden by expanding it, right? I can't tell you how many times I heard Democratic lawmakers in my state say "but it's free money". Bullshit, there's no such thing. The Federal Government pays 100% of the expansion for the first year and then it tapers off, putting significant costs on the state in the long run. Kentucky and Ohio are great examples, the poor bastards agreed to do it and budgeted the costs out to 2022. Then, miraculously their costs more than doubled. Illinois? Their Medicaid costs are now four times the original predictions.
It's classic bait and switch, a year of costs covered for a lifetime of debts. In my state, thank God we had the sense to say "fvck off" and put that money in a rainy day fund. After the hurricane this year, that wisdom saved lives and homes. Literally.
