Recall that McCain was up by double digits in two different polls from two different groups after the convention, then PPP started with their string of polls that suddenly showed a tight race. In fairness however, their last poll was pretty close to the results, and other pollsters, including the conservative Civitas Institute, were showing the same numbers as PPP along the way.
The only thing I’d question is the sudden drop that PPP showed directly after McCain showed a big lead.
What is it that convinces you that Jensen had some part in Obama’s moving his resources from GA to NC?
After the GOP Convention, McCain and Dole rose in the polls in NC. At that time, Nate Silver of 538, doubted Obama could carry NC. It looked like a triple win for the GOP in NC (McCain, Dole, and McCrory). Then the stock market crashed and voters wanted to punish all Republicans. Burr trailing right now is evident of the GOP brand in the dumpster. Hopefully, after a year with the recession still in effective, people will start to blame the Dems for economic woes.
