For a presidential candidate who believes she hasn’t had a gaffe, Michele Bachmann says some truly remarkable things.

The quote that got the most attention yesterday was Bachmann’s assertion that, if she were elected, “we wouldn’t have an American embassy in Iran.” It was amusing, of course, because there hasn’t been a U.S. embassy in Iran for several decades, though Bachmann’s campaign has an almost-plausible explanation to defend the context of the remark.

But some quotes can’t be explained away so easily. Take this extraordinary comment Bachmann made in Iowa, when asked about the legality of public school science classes teaching religion.

“I think what you’re advocating for is censorship on the part of government. So the government would prohibit intelligent design from even the possibility of being taught in questioning the issue of evolution. And if you look at scientists there is not a unanimity of agreement on the origins of life…. Why would we forestall any particular theory? Because I don’t think that even evolutionists, by and large, would say that this is proven fact. They say that this is a theory, as well as intelligent design. So I think the best thing to do is to let all scientific facts on the table, and let students decide.”

So, to review, Michele Bachmann doesn’t know what “censorship” means, she doesn’t know what evolution is, she doesn’t understand what constitutes “science,” and she has absolutely no idea what a “scientific theory” is.

Later, the right-wing Minnesotan told Glenn Beck that a “new axis of evil” is forming, which will include “North Korea, the Chinese, Russia, Syria.”

Remember, Bachmann isn’t just a presidential candidate, she’s also a member of the House Intelligence Committee.
