Anyone else noticing a pattern here?
The ad in question can be seen here. And here's what FactCheck.org has to say about it (emphases mine):
The Obama campaign strikes another low blow with a TV spot accusing Mitt Romney of “personally” approving a notoriously abusive tax-avoidance scheme and suggesting he may have paid “zero” tax. That’s badly misleading.
It wasn’t Romney who was avoiding taxes, it was Marriott Corp. And there’s no evidence to support the ad’s speculation that Romney himself paid no income tax, or that he did something illegal.
The ad opens with an unsupported insinuation that Romney isn’t releasing more federal income tax returns because some would show he didn’t pay any income tax in those years. The narrator asks, “Did Romney pay 10 percent in taxes? Five percent? Zero? We don’t know.” And the narrator might add, “We have no evidence to support what I just said.” But he doesn’t.
Instead, the narrator says, “But we do know that Romney personally approved over $70 million in fictional losses to the IRS as part of the notorious ‘Son of Boss’ scandal. One of the largest tax avoidance schemes in history.” On screen, we see similar quotes attributed to CNN, with the cable network’s logo prominently displayed. There’s so much deceit here we hardly know where to start.
The sheer number of falsities FactCheck.org lays out in this ad is staggering. Click here for the full run-down.
