The action in Nebraska is at the Congressional District level though and there Obama has some hope- although not necessarily where you might expect it. After he won the 2nd Congressional District's electoral vote in 2008 Republican redistricters moved more Democratic friendly territory from that district into the 1st and shifted more GOP friendly territory from the 1st into the 2nd.
That move is having the impact Republicans hoped it would in the 2nd district- Romney leads Obama 50-42 there and Perry has a 48-44 advantage as well. But in a finding that can certainly go into the 'unintended consequences' file Obama is now up 45-44 on Romney in the new 1st District and leads Perry by a 47-41 margin. Now it's important to note that the margin of error for the numbers in each of these individual Congressional districts is pretty high, but still, Obama would be trailing Romney in both the 1st and 2nd districts under the old lines.
