Peter Robinson has this to say at NRO:
"While the other contenders are frantically saturating the Iowa airwaves with 30- and 60-second attack ads—Romney is guiltiest, if only because he’s richest—Thompson has sat himself down, looked into a camera, and spoken for a quarter of an hour, calmly and straightforwardly making his case. I myself find this impressive—in a way, moving. Thompson seems to have stepped out of the eighteenth century. He trusts voters to think. And if the comments on YouTube are at all representative, plenty of people agree."
