I'm not so sure you can say that Obama is almost certain to win at the moment ... at the moment, the margin of error of most polls still has John McCain winning and (as it has been pointed out many times) there are reasons to believe that Obama may suffer worse from people saying they will vote for him (in polls) and then voting for his opponent than McCain will.
Right now I would say that it is more likely that Obama would win if the vote was tomorow but, with a month left and only really having to get 1% to 2% of voters in a couple of battleground states to switch their vote, McCain could still win this election.
