The latest polls show it doesn't exist:
Collectively, the new polls of the past 24 hours have done nothing to change the standings in the most crucial battleground states. Obama continued to hold leads of 2 to 3 percentage points in Ohio, Iowa, Nevada and Wisconsin, four states that currently combine with the states where Obama leads by larger margins to create a 277 electoral vote majority, seven more than the 270 needed to win …
Romney does slightly better in the national popular vote estimate, of course, but his 0.2 percentage point advantage there is only slightly better. The net gap is less than a percentage point. As the Cook Political Report's David Wasserman writes on Twitter, simply subtracting 4 percentage points from Obama's 2008 margins in each state produces a similar result: "He'd lose Popular vote by 0.7% but still win w/ 272 EC votes."
