Where and why is this ok?

I found an interesting article recently on www.americanthinker.com. Just a fantastic website for someone of my conservative leanings. Basically, the writer asks where in the Constitution the Democrats find that allows them to pass a Bill for Public Health Care. In the words of Boondock Saints .... no where. Pelosi, when asked this question, responded to the reporter with, "Are you kidding me?" The very thought was so completely out of her mind that she didn't know how to respond. You know, Madam Speaker. That one document that strictly lays out what Congress can and cannot do. Anyway, the following article is the one I'm talking about.
