There is a simple way to force even the democrats to want to repeal this thing. As written the law allows exemptions to be handed out solely at the discretion of the administration. Obama and his lackeys have done so for favored groups repeatedly. Trump can simply enforce the law as written with no exemptions for any groups, they will be begging to have ObamaCare repealed.
Can Trump use and EO to raise the penalty to $10,0000.00? That would get all of the people to push their representation to pull it.
