Michele Bachmann's presidential campaign is fading fast after an unmemorable performance in the Republican debate. I can't say I'm sorry. The Tea Party is, on the whole, a force for good, and the last thing america needs - apart from a second Obama term, of course - is a country-club Rino (Republican in name only) in the White House. But Bachmann is a creationist - that is, she espouses scientific claims that can be shown to be untrue.  This drives me nuts. Evolution is technically a "theory", but it is one without which the entire science of biology would collapse. Please don't confuse it with manmade global warming, which is supported by a far more fragile consensus. Conflating the two suits both Right and Left. Don't fall into the trap.
