The other issue is that other polls show Obama leading in early voting......there is no official release of early numbers yet. Everything is just polls, so they could be wrong.
On Tuesday, the suburbs vote. After that, they count the absentees (note: none of the exit polling of "early voters" can capture absentees, yet in Lee County which I examined last night, absentees outnumbered "early voters" by 3 or 4 to 1). These are disproportionately R areas, and in some cases (Warren County OH, for example) darn near solid R.
I could still see a number that would concern me, but as of right now, I think McCain won the election and won it by perhaps 52-48%.
