All this is moot anyway; the only poll that counts will be on November 4.
I agree, but polling like this can spread despondency and teeth-gnashing among our foe. It might also cause moves of desperation by the Obama camp that can be exploited.
Actually this is the Gallup poll that everyone used to cite. It only occurs every few weeks. These rolling daily tracking polls are recent creations.
And of course November is the one that counts but this gives us a boost of much needed energy for our side. Now we can see victory. We just need to finish the work we are already doing.
