First of all, I don't want to demean Muslims and Atheists. I know many fine members of those groups. But in hyper Christian America, if you believe the news media, they are the scourge of the earth.
Also, in the eyes of mainstream news media, the Tea Party was a big thing because they act so crazy that they make great spectacle.
So, it's only the news media that built the Tea Party into a so called major force in politics and now they are making a big deal that "Wonders and Horrors" the Tea Party isn't that big of a deal (except for what we make it).
As a matter of fact since every GOP official and candidate is now acting Tea Party crazy the news media has a new spectacle to follow, and they can throw the Tea Party over the side of the boat on which they allow people to be noticed in their rarefied pages.
