Yes - it was after Romney’s trouncing of Obama in the first debate and prior to the hurricane taking Romney completely out of the news cycle with Obama dominating the same, followed by Christie going all over the news networks gushing with praise for Obama - over the top praise.
In the end I don’t know that it would have altered the ultimate outcome, although it probably did flip a few of the very close states...probably Florida would have been in Romney’s column as that was a less than 1% margin and all of that with the hurricane, etc. was enough for at least 1% of the vote to switch sides...but just Florida was not enough.
If Trump wins this election, I will believe it was meant to be.
