Top aides to the GOP's presumptive nominee Mitt Romney were at a loss today to explain the candidate's recent slide in a series of national polls which show Romney dropping anywhere from seven to nine points behind the president as the nominating conventions approach at the end of this month.
"It's the middle of summer. It's the doldrums. It's the middle of the Olympics," a senior Romney adviser told reporters gathered for a briefing at the campaign's Boston headquarters. "There's not been any national news, anything that would push these numbers from minus-three to minus-nine points. That's a huge shift. You have to have some kind of precipitating event to move numbers like that."
