Nate Cohn sees several:
With Obama’s most straightforward path to the 270 enduring with five days to go, the last thing Romney needs is a weak southern flank. But Romney spent all of yesterday in Florida, and it’s not hard to see why. CBS/NYT/Quinnipiac and other polls released yesterday pointed toward a slight Obama edge in Virginia and a tied race in Florida. On average, Obama leads by .7 points in Virginia and trails by .8 in Florida in polls conducted since the final debate. Unlike the other battleground states, Romney’s standing in these averages may be inflated by outlying polls from second-tier pollsters showing Romney ahead by 5 points.
