This is getting delightfully convoluted:
A second source, said to be "close to Senator [Harry] Reid," has told CNN's Dana Bash that Reid's original source for the claim that Mitt Romney "didn't pay any taxes for 10 years" exists, is a "Bain investor" and a "credible person."
They're having a hard time keeping up at Daily Kos. I wonder if Romney will tell CNN to "put up or shut up," too. Apparently, this is Reid's plan: Build a case against Romney on the word of an anonymous source, and then back the story up with an army of anonymous sources. It'll keep the story alive for another day into the weekend, and now the Sunday news shows will spend the bulk of their time talking about whether or not Mitt Romney paid taxes for a decade. It's nasty, effective politicking, and it appears to be working. Romney still won't release his taxes, so he looks ineffective, creepy, and secretive.
Let's just allow ourselves to imagine for a moment that this story is true, and think about the implications of that. If this story is true, that would mean that not only did Romney not pay taxes for a decade, but it would mean that he was bragging about not paying his taxes for a decade. Would that help him or hurt him with the Republican base? I honestly have no idea, but I know how it would play with independents.
