What I think is happening, is this – the polls’ headquarters were based deep in liberal territory, where the assumption was that Obama’s candidacy would actually create a groundswell of pro-democrat voters unseen in the country since 1932. That McCain is more experienced with the key issues than Obama was ignored, that the historical significance of the debates shows that the effects appear several weeks later was also ignored. That the economy could be as reasonably blamed on the democrat-controled Congress as on the republican President was never considered. That character would be a salient factor in the decisions of voters was rejected out of hand.
The polls are wrong. Make your own mind up, because your vote will matter.
