I see from your pings you seem to have a great interest in the polls. Is it a hobby or a profession? (Also, you sound as though you want McCain to lose. Are you an Obama supporter?) Check out Rove’s electoral college map. It has been changing over from undecided to red lately, including FL and others. VA, which was blue recently is now trending away from Obama, yet Obama has not picked up anything during the same period. The trend for the moment is quite clear and decisive, although much can happen in seven weeks.
Also, you sound as though you want McCain to lose. Are you an Obama supporter? I absolutely DO NOT want Obama to win. But the last Republican to win the presidential election in a landslide was GHWB, who add two advantages that McCain doesn't have this year: (1) the very long coattails of Reagan, and (2) going against one of the worst candidates that the Democrats have put up for president in my lifetime.
McCain has the opposite problem with GWB, and say what you want about Obama, his campaign is highly effective, if not nasty (ask Hillary her opinion about that after this election).
The cards are stacked against McCain "winning in a landslide" or even a cakewalk.
