"The Undefeated" — that movie about Sarah Palin — unwittingly shows why she's not a good candidate for President.

As you know, I saw the movie last week and thought that as a movie, it was pretty bad. It's a separate question — though Palin fans have a hard time seeing it — whether the movie supplies us with material that is convincing on the subject of whether Palin should run for President.

The material — which impresses some people, even to the point of getting confused into thinking that the movie is good — shows Sarah Palin's rise to power in Alaska and her excellent achievements and immense popularity as governor. The problem is that all of this happened in the context of boldly and bravely challenging the corrupt Republican establishment. This made her very popular with Democrats in Alaska. She worked in a bipartisan way, mainly to extract money from oil and gas resources in Alaska, and that was popular with everyone, pushing her ratings above 80% in Alaska. She was raking in money for Alaskans and challenging the big corporations (and their inside dealings). What's not for Democrats to like?

But once McCain brought her in as the vice presidential nominee and she launched into ripping up Barack Obama, her ratings plummeted in Alaska. And non-Alaskans never got up to speed about the things that had made her popular in Alaska. Can the movie make up for that now? I don't see how.

Suppose Palin-haters or Palin-non-lovers went to see this movie and absorbed the information about what originally made her so popular in Alaska. They aren't going to start liking her. Even if they were fair enough to recognize her early achievements, those achievements don't translate into the presidential realm. Where are the big corporations with ties to corrupt Republicans that she's going to fight now?

More importantly, Governor Palin's greatness came through working with Democrats! How would President Palin work with congressional Republicans? It can't happen now. What made her great in Alaska is now lost. It was lost in Alaska, after the '08 election, which is why — the movie shows this — she had to resign as governor.

Democrats were central to Sarah Palin's greatness: That is the argument in the movie. If that is true, there is no greatness upon which to build a presidential bid.
