It was not found unconstitutional? They said that you could not use it under the Commerce Clause, that in and of itself makes it unconstitutional. They did suggest it can be used as a tax, but the original use of it was unconstitutional.
However now Obama has to run on what is the most unpopular law in the past century, and run on it as a TAX. Dude you think the Tea Party was tough before, wait till they attack Obamacare as the biggest tax increase ever!
