Why Does Perry Talk Nonsense?

Frum accuses Perry of not reading his own jobs plan:

Doesn’t Perry understand that his own so-called jobs plan–which is really an industry wish list for enhanced fossil fuels production–is entirely predicated on a doubling of energy prices over the next 18 years?

Jonathan Bernstein's alternate theory:

Perry is confronted with a tough problem, and is taking a sensible way out. The tough problem is that doing policy in the GOP nomination contest is almost impossible. What motivates Tea Partiers and other enthusiastic primary voters? A lot of it is mythical… It's not Rick Perry and Mitt Romney who aren't serious; it's the party they're trying to lead.
