Governor Palin's claim that "Israel is in jeopardy of course when we're dealing with Ahmadinejad as a leader of Iran" led viewers to try to learn more about this leader even if they could not spell his name. They searched for [Achmadinijad], [Akmadinijad], [Akmadinajad], and the correct Ahmadinejad. Some did not even try, instead looking for [president Iran] and [Iran leader]. The Governor also referred to General McKiernan, the U.S. military leader in Afghanistan, as "McClellan", sending viewers in search of McClellan, general in Afghanistan, General McClellan Afghanistan, and general Afghanistan surge. Some searchers eventually did find the correct general, but not that many.
