The Rasmussen "Presidential Approval Index": Is This Newer Measurement Worth Anything?
Some commentators on the right have been pointing to an interesting number that has been coming from the Rasmussen daily tracking poll, which Rasmussen bills as the "Presidential Approval Index," which Scott Rasmussen only began bringing out in late 2008. The key questions then are: What is this number, and is it a valid measurement of real popularity? In an interview today with TPM, Rasmussen defended the index's validity against some harsh criticism, saying that intensity of opinion -- the true figure measured by his index -- does indeed matter.
The thing to remember is that this is not simply subtracting all the respondents who disapprove of President Obama from the people who approve. Instead, Rasmussen takes the numbers who strongly approve or disapprove, and then performs this math. As of today, that index number is -10, compared to an overall rating of +1 in Rasmussen's daily tracker.
It would seem at first glance that this number can skew negative -- that is, the people who disapprove of a president are inherently more likely to feel strongly about it, compared to a certain level of lukewarm support for a president. For example, the 2004 exit poll put George W. Bush's strong approval at 33%, to strong disapproval of 34%. But his overall approval was 53% to disapproval at 46%, and he was re-elected 51%-48%.
I asked three prominent polling experts about this, and they all lambasted it.
And yet, you just know that there will be wanks who will be all over that disingenuous douchebagitude like stink on cheese:
A Rasmussen poll released today shows Obama's Approval Index sitting at minus 12 percent, his lowest number yet. 40 percent of American voters now strongly disapprove of Obama's performance, compared to just 28 percent who strongly approve.
