The RATS understand perfectly well that if the American "swing voters" ever learn the truth, they may never win another election.
exactly right. this is the demographic they fear.
You can expect lots of "disavowing" after the series is shown. First the Dems who haven't yet said anything will disavow the actions of those who have, and the ones who have will disavow having said them, or say they were "misinterpreted".
I don't think any but the committed 30% of solid Dems, and not even all of them, will buy it though. The Dems are toast. Whether the furor dies down by November, that is the question.
