Romney's Lafferism

I'd been under the impression that Mitt Romney had thus far resisted the urge to claim falsely that reducing tax rates is likely to increase federal revenue. Brendan Nyhan shows me that it's not true. Romney's explained that " you lower taxes enough, you create more growth" and "if you create growth, you get more jobs" and thus "You get more jobs, more people are paying taxes. You get more taxes paid, the government has more money by charging lower tax rates."

This is not only bad economics, but seems to indicate a failure to grasp some of the basic principles of logical inference.
