@dlowan,
Yeah. Indeed. It now looks beyond obvious that a talk show is likely one of the venues where she'd fall on her ass immediately. Her inability to either talk or think coherently, particularly in the seat-of-the-pants mode of a talk or interview show, puts this one out of reach....once the talking points are exhausted, there'll be vast expanses of white nothing.
Heavily rehearsed, diligently protected, figurehead Sarah together with an audience of the sort she spoke to at rallies looks the only plausible scenario. That was the route that allowed Bush to achieve the nomination and presidency but she's even less functional so it would have to be quite an effort.
For now, she's the darling of the talk radio crowd and the religious right crowd. That ends immediately they decide she can't be a winner. Why they assume she might possibly work out is a puzzle. It's quite possible that they are just temporaily using her now as a symbol (true for Joe the Plumber too) to do one of the main propaganda tasks they do daily...attack the media and the Dems and moderate Republicans who've gone apostate as elitists who despise the regular folks.
