I don't understand why they'd only run it once

Last night Rick Perry appeared on the Jay Leno show and this ad ran in Iowa. The campaign announced it would only run once. Perhaps they don't have the money to keep this ad up in Iowa. But it seems to me the ad strikes the right tone.

Frankly, they should have run something like this right after the debate performance. Now, the least they could do is run it a few more times. Team Perry has some really well done commercials. And of all of them, this one is rather necessary to get out there.
