I wish we would not throw the words “subsidy” and “exemption” around as if they are the same thing. We know Congress is accustomed to enriching themselves at the expense of constituents, and they are just as willing to have the taxpayer foot the bill for their exotic health insurance plans. But they have by no means exempted themselves from partaking of the Federal exchanges as far as I know.
Except for the "paying for it" part.
