The SCOTUS gave them the power to mandate what we spend our money own on.
That was a battle lost, but I am not so sure a war lost. Obummercare got redefined as a tax, in the grand Roberts cop out. (Four others, including the problematic Kennedy, agreed in opining that there was no way to salvage this hunk of ordure.) But there is a second chance to approach such taxing: not all taxes are constitutional (you couldn’t tax someone for being a Jew, for instance). That issue didn’t get explicitly brought up before the USSC in that infamous case. Look now at what, say, Hobby Lobby is now being “taxed” into doing for the sake of its owners’ faith. There is still a chance for the USSC to do something sane, after having kicked the can an unseemly distance down the road.
