No wonder polling averages remain mainly flat following this world-class gaffe.
What this survey makes clear is that even after national headlines, some kinds of stories just don’t register to busy Americans who have more things to do than follow every jot and tittle of the news. Which is one reason why the attention devoted to gaffes dwarfs their actual impact at the ballot box.Now, granted, if Mitt Romney and outside GOP groups feature the quote in heavy advertising from here to November, more people will hear about it. But it's not as if they would otherwise not be advertising; the question then would be how much additional effect that particular quote has compared to whatever the alternative would have been. Given the limited effect of campaigns overall, and that advertising is only one part of campaigns, and that this would still be only a subset of all advertising...I'm pretty skeptical that having this particular one out there compared with whatever alternative would have been used will make much of a difference at all.
But that's just informed speculation. The numbers that we have are information. And: nice catch!
