Those polled were not characterized by CNN, which means they weren’t “likely voters,” the crucial criteria. If they had been, CNN would have been sure to mention it because it enhances the value of the report.
That said, temperamental, fickle, lightweight Sarah Palin, who unceremoniously abandoned her office in little Alaska because the heat in the kitchen got too hot, is not suited for the Oval Office, where the flames are several orders of magnitude more intense. Even though the CNN poll may not be fully reliable, we can be sure the American people, to their credit, have sussed that much out.
Memes like that have a diminishing market. Nice try though.
