There is no way they'd be able to pull that off. The people who would be ordered to do something like that still have a conscious. This is America, not NAZI Germany, and our laws, Constitution, and society today are so far removed from NAZI Germany that I don't think it's going to happen.
Pretty much, I think someone would have to manufacture a bunch of souless androids to do it. No one I know wants to put conservatives in concentration camps, or cut off their healthcare.
