We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I don't think in my lifetime I have ever witnessed quite a campaign in which the wife of the Presidential candidate has been sequestered lest she voice yet another sweeping generalization that can be rightfully interpreted as denigrating both the American system at large or the values of other Americans; or in which the Vice Presidential candidate has been sequestered from press questioning lest he once again in an interview or an impromptu says something that either is so bizarre that it makes no sense at all or serves as a good argument not to vote for his running mate; or in which the Presidential nominee himself knows that if he stays on the teleprompter he has a good chance of winning, but if he wades in to banter with the crowd there is equally a good chance that he may say something so disturbing that the entire facade that he has so carefully constructed simply collapses.
The short clip would have been much more interesting - and potentially damning - if it had been dated on your post. When did Michelle Obama utter those words? This year? No. Last year? No. How many years before? And what, indeed, did Mr. Obama accomplish in the meantime to make her change her mind? So many questions; so little time.
Yeah, but it's the best excuse he provide on short notice. Distract into irrelevant discussions. They do it well - better than we do at resisting the temptation, in fact. The trick is to pick something close enough so that the conservative is lulled into thinking "well, if I just knock down this simple point, we'll be home free."
As to VDH's point, get used to it. We saw the beta version with the Clintons, when Hillary would appear and disappear throughout the campaign. It has now been shown to work, and will be used again.
