This Young Turks clip shows exactly how NOT to do fact-checking.
This one involves Obama's assertion in the debate that Romney is offering a $5 trillion tax-cut and that, in so doing, will be forced to either blow up the debt or cut middle-class tax breaks like the deductions for mortgages and charitable donations.
So here's how CNN fact-checks this argument. After conceding that Mitt Romney has indeed proposed a 20% tax-cut across the board, CNN then says:
Romney says he will offset that by closing loopholes and reducing reductions.So that's what fact-checking has become? Just taking someone's word for it?
So if we take him at his word, the verdict that Mitt Romney will cut taxes on the wealthy by $5 trillion dollars is false.
Here it is at the 4:15 mark, but I would advise watching the whole segment just to see how Cenk and Ben Mankiewicz skewer the network for this obvious fact-checking fail.
