Responding to the early polling showing President Obama with a bounce -- and lead -- after the two conventions, Romney pollster Neil Newhouse argues in a memo to reporters that the presidential contest "has not changed significantly."

"Don't get too worked up about the latest polling," Newhouse writes in the memo. "While some voters will feel a bit of a sugar-high from the conventions, the basic structure of the race has not changed significantly. The reality of the Obama economy will reassert itself as the ultimate downfall of the Obama presidency, and Mitt Romney will win this race."
