|Rasmussen Polls Since w/Leaners Distinction was Added (7/9/08)*|
|State||Date||w/o Leaners||w/Leaners||Change||Undecideds Drop|
|*The "with leaners" distinction was added to reports that were released beginning on 7/9/08. The date on which these polls were conducted (The ones that these releases were based on) stretches back to 7/7/08.|
**Rasmussen has only conducted one poll in these states. Therefore, the difference was taken from between the with and without leaner numbers within the same poll in these cases.
***Previous poll had been taken after "with leaners" change had been made.
Overall then, there is still a bias toward McCain in cases where "with leaners" data is replacing w the data that does not include them. As I've said, this isn't going to hae major ramifications at the outset, but over time, once a series of polls have been conducted, that collective difference could have a huge impact on what FHQ and others are doing with their electoral college analyses. In the only instance where a state has been polled by Rasmussen more than once since the switch, the results cancelled each other out. The first poll gave McCain a one point edge with leaners while the poll that followed two weeks later saw Obama with the same advantage. Such a result likely won't be the norm, however. In Ohio, for example, using one version or the other shifted the Buckeye state's 20 electoral votes from Obama to McCain and back again. And though that is the only case of a change thus far, that list is likely to grow in the future when new polling data is released.
So looking at the map, we see that using the without leaners data -- the type that was used prior to July 9 -- shifts the map in Obama's direction with the electoral vote tally reverting to the 298-240 margin that had been in place for most of July until the new Ohio poll surfaced last week. That four point change in Ohio triggered just a 0.34 point change in our weighted average, but that is all that is necessary to move 20 vital electoral votes from one candidate's column to the other's.
It could be said that all were arguing over is whether Ohio is a toss up favoring McCain or Obama when the real point is that the Buckeye state is a toss up. Period. It doesn't really favor anyone. That's a valid point. However, there are differences in other states -- obviously -- but one poll has not been enough to affect change in those cases. Further polling, though, may bring about that change.
Note: I don't know how regularly I'm going to update these figures, but I have built them into my spreadsheet and I'm tracking the differences. When and if any changes occur -- major or minor -- I will bring them to the attention to our readers.
