The Democrats and the left in general have been trying unsuccessfully to smear and marginalize the tea party movement for over a year now. I think that in the face of a storm of opposition, they decided to try for a Hail Mary pass; they picked a charge perfectly calibrated to excite the prejudices of their allies in the media and get big coverage. In the last, at least, they were successful.
But that was simply preaching to a very willing choir. In the arena of public opinion, the “Hail Mary” failed. No such video exists. If it did, we’d all have seen it a thousand times by now. Andrew Breitbart was confident enough about the un-video to publicly bet $10,000 (since raised to $100,000) that nobody could produce one. So far, there haven’t been any takers.
Read the whole thing for Collier's theory about what might have been happening behind the scenes as the Democrats planned their stunt.
