Not a huge Palin fan, but this is a great article:
1. Palin cost McCain the 2008 election.
She didn't. CNN's 2008 national exit poll, for example, asked voters whether Palin was a factor when they stepped into the voting booth. Those who said yes broke for McCain 56 percent to 43 percent.
Before Palin's selection, remember, McCain suffered from an enthusiasm gap. Republicans were reluctant to vote for the senator from Arizona because of his reputation as a maverick who'd countered his party on taxes, immigration, drilling in the Arctic National Wildlife Refuge and "cap and trade" climate legislation. But Palin's conservative record in Alaska and antiabortion advocacy changed the Republican mood. With her by his side, McCain's fundraising and support from conservatives improved. It wasn't enough to beat Barack Obama -- but McCain probably would have lost the presidency by a greater margin if he had, say, selected independent Sen. Joe Lieberman as his running mate, further alienating the GOP base.
Yes, it's possible that Palin's conservatism and uneven performance on the campaign trail shifted some voters to Obama's column. But even if Obama picked up some anti-Palin votes, he surely didn't need them: The economy was in recession, Wall Street was in meltdown, and the incumbent Republican president was incredibly unpopular. In the end, it's impossible to know how McCain would have performed if he hadn't selected Palin -- politics does not allow for control experiments.
