Third consecutive poll to show Obama up by double digits
remember the primary. That's all I'm gonna say.
......however, there were several dynamics at work in the primary that aren't at work here: for one thing Hillary's win came largely from the margin she racked up among early voters, who voted during the "Hillary is inevitable" phase. This time around, early voting, if anything, will likely benefit Obama. Also, if John McCain cries a week before the election, he'll be laughed out of the race. However, if Sarah Palin cries a week before the election...see where I'm going with this? 
Of course, but the primary was a bit different. Because of the high Obama lead, many Independents voted in the GOP primary, because they thought their vote would have a bigger impact there. Not to mention cry-baby Hillary, who used to tighten her grip on the state's Democrats a few days before the vote. But what stands out ? Despite all of this Obama still managed to get more votes than McCain in the primaries and there's no reason why this shouldn't be this way in the GE too.
