In fairness, just as there are people who hate Palin for the effrontery she shows in daring to draw breath at all, there are those who love her with a devotion better suited for a religious icon.
I hear from both camps, often. And while I don't think both sides are equally wrong (after all, the acolytes of the Doniger school openly reject reality more than any so-called creationist), I don't think either position is laudable or sufficient.
Sarah Palin is neither savior (that job has been taken by the current president, or didn't you know?) nor is she satanic. She is a politician, a species of human like the rest of us.
I'm fairly certain that if you read many of her public-policy positions but concealed her byline, many of her worst enemies would say "that sounds about right," and some of her biggest fans would say "that sounds crazy." But most people would say that her views are perfectly within the mainstream of American politics. She may be more religious than coastal elites in the lower 48, but that is something some bigots need to get over anyway.
I'm happy about the books she's selling thanks to the controversy over her, but that doesn't mean I think these controversies are justified. Palin holds no public office and, as of yet, is not running for one. But the Associated Press assigned 11 reporters to "fact-check" her book, while doing nothing like that to fact-check then-candidate Obama's or current Senate Majority Leader Harry Reid's no doubt riveting book.
As it stands, my sense is that Palin is good for the Republican Party but not necessarily great. She generates enthusiasm among, and donations from, the base. But she also turns off many of the people the GOP needs to persuade and attract. That could change with this book tour, and I hope it does. Whether she's ready or qualified for the presidency is another matter. But the presidency is a long way off, and besides, that's what primaries are for.
