The problem with this question should be obvious: It was asked only of Republicans and offered just two choices: Bush, who was president at the time and Obama, who was still a junior senator from Illinois. "If you ask the vast majority of Louisiana Republicans to identify the leader most responsible for the Katrina response," the conservative Louisiana blog The Hayride argued, "you’re going to get Kathleen Blanco and Ray Nagin as the answer. Replacing those two on the ballot with Barack Obama so that the only choices available are Bush, Obama or 'not sure' is malpractice, and mean-spirited malpractice at that....The question was designed to force Louisiana Republicans to trash the former president in “It’s Bush’s fault” fashion. And that was transparently obvious to the respondents. Anybody could see what they were trying to do. So 72 percent of those polled basically told PPP to do something anatomically impossible. 44 percent chose the most non-responsive response they could, which was to say 'not sure.' And the other 29 percent went even further and gave the in-your-face answer of Obama.Here's what you need to remember about surveys: they don't primarily report opinions, or predicted action; they report how people answer the specific questions asked in the circumstances under which they are asked.
In many cases, the way people answer questions from a pollster does in fact have a close relationship with their opinions; in many cases, it can predict action. In plenty of other cases, however, that's just not the case.
For a common sense rule of thumb...the closer a question is to something that respondents have been actually thinking about, the better the chance of the answer indicating something we would normally think of as a real, stable, opinion. The closer a question is to something that someone is already planning to do, the better it will actually predict actions. So, in the classic case, asking someone who they will vote for tomorrow is going to be an excellent way of finding out election results in advance; asking someone who they would vote for if an election scheduled three years from now was to take place today is going to produce a very poor prediction of future actions.
So, yeah, feel free to have fun with this sort of thing...I have no problem with PPP for doing it. Just be careful not to read it too literally or take it very seriously.
And: nice catch!
