The mainstream media and Democrat operatives, as good post-modernists, cannot change the facts of the world, but they can frame those facts to suggest their preferred interpretation of them.
Fact: John McCain nominated Sarah Palin to be his running mate.
Spin Attempt #1: She's the second coming of Dan Quayle. Like Mr. Quayle, nobody who mattered knew her and she wasn't a regular on the Sunday thumb-sucker shows. And she can't be qualified, otherwise our masters in the Beltway would have lunched with her and would tell us so.
However, Mrs. Palin failed to cooperate by responding to bright lights like a deer in the headlights. (This might have something to do with her beauty pageant experience.)
Spin Attempt #2: She's trailer trash with too much hair, too many kids, and her youngest is probably the fruit of an incestuous union between her husband and her daughter.
The conspiracy theories to support the latter hypothesis utterly buggered belief and couldn't pass the laugh test. All they did was to make the extra-chromosome wing (Al Gore's words) of the Republican party, i.e. me, furious. (Why yes, I have gone back to calling myself a Republican.)
Spin Attempt #3: (whispered) She's a bad mother with an out-of-control 17-year old daughter, taking dangerous risks flying on airplanes (imagine that, airplanes) while pregnant, and doing G-d-knows-what in the Governor's office while she should be barefoot and pregnant in the kitchen.
This also failed because Democrats can't keep a straight face when they say a wommon's place is in the home. To add insult to injury, the Religious Right failed to drop her like a hot potatoe when they learned of daughter's out-of-wedlock pregnancy.
Spin Attempt #4: OK, Sarah Palin is beleaguered from all of the above and is really Thomas Eagleton, v2.0 and the Republicans will come to their senses and drop her from the ticket.
Then Mrs. Palin gave a speech that a lot of people watched (to find out what all the buzz was about). It's hard to maintain 37 million instances of the "who you going to believe, me or your lying eyes" narrative. Meanwhile, a lot of Republicans remembered how tasty red meat is and are now saying they'll vote for Sarah Palin and that guy with her.
Spin Attempt #5: [speaking of the messiah] Sarah Palin used... sarcasm. She knew all the tricks, dramatic irony, metaphor, bathos, puns, parody, litotes and... satire. She was vicious.
Well, being the "attack dog" of the ticket is the main job responsibility of the Veep. Obambi was in her sights and she put lead on target.
This brings us to now.
Spin Attempt #6: Sarah Palin is Spiro T. Agnew v2.0. Given the poisoned atmosphere of recent rumor-mongering and hard-to-deny media-bias, she's going to make the campaign all about the press bias and Leave Obama Alone! Please, please, Leave Obama Alone! Leave Obama Alone! Call us nattering nabobs of negativity, please. Leave Obama Alone! Call us an effete corp of snobs. Leave Obama Alone! Please!
Here's a bit of meta-analysis. When the story changes each day, you don't have to pay much attention to it, or take it particularly seriously, because it'll be different tomorrow.
Meanwhile, I've got a suspicion that doesn't have sufficient data to support it. Mrs. Palin appears to have a track record of taking on powerful enemies and hanging tough against them. Something had to sustain her through the viciousness of this last week's attacks upon her family from the ends-justify-the-means left. You might call her an Iron Lady, but that title is currently held by Dame Margaret Thatcher. Don't take my word for it. Just keep your eyes open and we'll see.
