Unfortunately for O'Donnell that is not quite true. The Sept 14 poll is the one that counts, which is why losing ground in the polls between July to August is a significant blow to her chances.
Unless of course you believe Matt Moran (O'Donnell's campaign manager) that Rasmussen is colluding with the NRSC to make her look unelectable (lol).
And you pro-Castle guys better get used to the fact that we conservatives aren't concerned with Castle winning under any circumstances.
Castle is a liberal who shouldn't be rewarded for his liberal votes in the House with a Senate seat.
So, Castle could have a 50pt lead and I could care less.
