Are you sure that there is only one poll that counts?
That was the attitude the GWB campaign used in 2000 and 2004. So they did what they could to obscure their real policies, ran on largely hollow demagougery (SBVFT? Inveted the Internet?) And then thought they could govern as though they had a mandate.
And we have seen where that has left GWB. He is now such a lame duck that when he comes on national media (TV and Radio) and gives an address saying "The Nation Is in trouble - this bill needs to be passed to save it" That not only does the pulbic not believe him or follow him, but HIS OWN PARTY IN CONGRESS doesn't follow.
As a result, our enemies abroad (and we have them) are largely ignoring any diplomatic pressure the US is trying to apply to reduce the threats to us, just as Bush is being ignored by Congress.
So, do you honestly think that if McCain/Palin win in November, that they will get enough of the PUBLIC's support (as opposed to the voting public) that they will be able to govern?
Do you really think that McCain will even break 50% approval ratings 6 mos into his administration?
