Why am I not surprised? I had never heard of ResistNet before I attended the Tea Party Express stop in Madison a few days ago, so I decided to check it out. Turns out that ResistNet was created, and is presumably controlled, by a GOP public relations firm called Shirley & Banister Public Affairs. SourceWatch has more details.
ResistNet's motto is "Home of the Patriotic Resistance." Seems like "Home of the Republican PR Operatives" would be a lot more accurate. Or maybe "Home of the uninformed teabaggers who are too dumb to figure out that they're being used."
To be fair, I should point out that the left also has its share of astroturf front groups, although they're not nearly as pervasive as those on the right. The Democratic and Republican Parties pretty much work from the same political playbook, but in this arena Republicans are much more successful. In part this is because Republicans and business interests simply have far more resources to throw at such efforts, but also because it's easier to manipulate the grassroots right, which is generally both less educated and less politically informed than the activist left.
