... Sarah Palin isn't Dan Quayle. She is extremely smart -- much smarter than the average media star who will eventually be interviewing her -- and she is very politically skilled as well. She didn't go from obscure small-town city council member to Governor to Vice Presidential nominee by accident.
I don't think she's extremely smart.
Palin may be aggressive and sure-of-herself, but she hasn't exhibited "smart". She may be, but there's no evidence of it so far.
Up until now, she's demonstrated the same level of smartness equivalent to a run of mill press flack (think Tucker Bounds). Greenwald is suggesting that's enough to run the gauntlet of "tough" interviewers like Charlie Gibson and Larry King. That maybe true and she may get away with it before November, but I think that the greater probability is that she will stumble and reveal a mental void when it comes to understanding the issues of the day.
We'll see. After the last 8 years I don't think "Bush smart" will carry the day. It might, but I'm inclined to think it won't.
Part of that depends on the press, and right now there are wildly conflicting signals as to where the press is on this. Some say the press is supine. On the other hand there have been a number of voices showing resistance to McCain's stiff-the-media plan (Joe Klein, Barbara Walters, Jay Carney - sortof, Roger Simon and Jeanne Cummings of Politico).
