Well, I suppose everyone is pretty fed up with this epitome of stupidity and ignorance, so providing any extensive coverage would be excessive. You can read a more extensive coverage here (including a link to the “I am not a witch” video game).
But in case you really want to relive some of O'Donnell's highlights:
O’Donnell’s campaign to end masturbation.
O’Donnell the young earth creationist (complete with the “just a theory” and “if monkeys evolved into humans, why are there still monkeys).
O’Donnell on why we should stop encouraging the use of condoms and how AIDS would go away if gay people just stopped having sex.
O’Donnell on those awful scientists who have been crossbreeding humans and animals in the US and come up with mice with fully functional human brains.
O’Donnell’s classified information showing that China is plotting to take over the US.
O’Donnell on why she doesn’t celebrate Halloween.
O’Donnell on becoming a Hare Krishna if she didn’t love meatballs so much.
O’Donnell failing the First (and pretty much every other) Amendment.
For the 2012 primaries she endorsed Romney: “That’s one of the things that I like about him — because he’s been consistent since he changed his mind,” said O’Donnell.
Diagnosis: The Platonic form of fail. It might actually be true that she never really consciously lies even though she tells a lot of untruths. Almost as stupid as Victoria Jackson. Hopefully neutralized by now.
