What happens when you get in too big of a hurry?
You make mistakes. And apparently Congress was in one heluva hurry... Not only did they eliminate their own insurance prematurely, they also forgot to write in a severability clause. For those who are not familiar with the law, a severability clause allows the remainder of a contract or law to remain valid and in force if for some reason one part of the contract or law was found to be invalid. And since there are several parts of the health care law that may well be found to be unconstitutional (the use of the commerce clause as the vehicle to make you buy health insurance chief among them.), without such a clause, it is all or nothing. If any of it is struck down, it all goes down in flames.
