What happened to the Romney campaigns take-no-prisoners vid suggesting Rick Perry’s not sharp enough for the big job. Still no word on why or how it got yanked from Youtube.

What if you ran for president to boost your book sales numbers and somehow found yourself the frontrunner for the nomination even though you’d never set up an actual campaign? Ask Herman Cain.

We’re not certain what happened here. But you’ll notice that late this afternoon the Romney campaign put out a campaign video mashup of all Rick Perry’s brain freeze moments from the debate. The charitable read of the video was that Perry wasn’t up to the challenge of debating President Obama. The less charitable interpretation was that Perry was just too big a doofus to be president.

A couple hours ago TPM Reader HW said it was a mistake on Romney’s part. And now as of about 10 PM on the east coast the video has disappeared from Youtube. It now reads “This video has been removed by the user.” Now, Youtube can be pretty glitchy. And things can be inadvertently overwritten. So we can’t say with any certainty that the Romney campaign pulled the video. And it may reappear as we speak. But it seems to have vanished.

We’ve reached out to both campaigns to try to find out what happened. And we’ll update you when we hear more.
