I don't think they can get away with it. Meaning it will cause, at least, a political revolution. Democrats will be thrown out of office in even BIGGER numbers than is going to happen already, and the law will be overturned. Obama impeachment would certainly be on the table, and passing it through a Republican controlled house, regardless of what happens in the Senate, as was the case with Clinton, will serve as a very time consuming and effective check on his ability to do more harm to our nation, in the event he is still in office.
If they can design it so it doesn’t look much like the theft that it really is, then they can get away with it.
