Why aren't Obama's global warming cars selling? Because they suck, they're too expensive, and global warming is a pseudo-scientific myth.
Peruse Chevrolet's February sales release, and you'll notice one number that's blatantly missing: how many Chevy Volts were sold. The number – a very modest 281 – is available in the company's detailed data (PDF), but it apparently isn't something that GM wants to highlight. Keeping the number quiet is understandable, since it's lower than the 321 that Chevy sold in January.
