US Senatorial Candidate Elaine Marshall attacked the profit margins of health insurance companies last night on News/Talk 1110 WBT's Pete Kaliner Show.  There's only one problem: she didn't actually know what the profit margin was.  If you're wondering, insurance industry profits were at 2.2% last year.  Not only is that far lower than many other industries, it's less than last year's Congressional raises.  It looks like someone is merely reciting the Liberal crib sheet without bothering to learn the facts.
