About That CNN Snap Poll...

So, the main thing I'm happy to observe in the CNN snap poll about the recently-completed Presidential debate is that, though the respondents overwhelmingly said they thought Romney won the debate, the two candidates' favorability numbers didn't budge an inch between the initial round of calls before the debate and the follow-up after it. Specifically, Barack Obama went from 49% favorable, 50% unfavorable to a 49%/49% split, while Mitt Romney went from 54% favorable to 42% unfavorable before the debate to 56%-42% afterwards. So Obama gained one net point, and Romney gained two net points. Big effing deal.

But, uh, notice anything funny about those "before" numbers? They show Romney quite popular and Obama only sort of middling. That's not what any other poll has found for the general electorate these days. I'll let the pollster.com polling averages speak for themselves: Obama's got a 51.9% favorability rating in the aggregate, against just 44.0% unfavorable, while Romney's sporting just a 43.6% favorable score against 49.1% unfavorable. So in most polling heading into this debate, Obama is a net 13.4% more popularly perceived than Mitt Romney, but in the group of debate watchers in the CNN poll Romney was 13 points more popular than Obama. That's a skewed poll for you.

Now, that doesn't mean the poll is meaningless. Among people who watched the debate, most thought Romney won. But the poll is also telling us that "those who watched the debate" may well have been a Republican-leaning bunch. But that very fact is deeply informative, or should be anyway, of our analysis of the reaction to this debate. Regardless of who's more energized to vote this year, Republicans were far more energized about this debate. And this debate still doesn't seem to have changed very many people's minds about either of the candidates. So it looks to me like, while the debate was unquestionably a "win" for Romney, it may have been sort of a trivial one. And right now, he doesn't need trivial wins, he needs wins that he leverages into big swings in the polls. So far, it looks like he didn't get one. (Of course, that statement can neither be confirmed nor rebutted until about next Monday, when the first batch of post-debate polls will start coming in.)
