Nancy Pelosi's having quite a day. First, she denied the existence of the GOP wave in last Tuesday's midterm. Now, we've gotten word that she's denying any knowledge of ObamaCare architect Johnathan Gruber. Obviously, you know Gruber as the arrogant MIT professor who helped write the Democrats' health care legislation. You also know him as a guy appearing in an increasingly large collection of videos in which he admits the law was built on lies and voter stupidity.
