For whatever it's worth:
http://fivethirtyeight.blogs.nytimes.com/2010/12/22/census-impact-on-2012-presidential-race-is-limited/A couple things to note:
-Under the 2012 map, Obama would still have won with 359 electoral college votes
-The outcome of every single Presidential election in the past century would have been the same had the 2012 numbers been used
The only scenario where I see the new allocation of electoral votes becoming a hinderance for Obama's re-election chances is if the 2012 results look almost identical to the 2004 election results. Barring that, the outcome of the 2012 Presidential election will have little--if anything--to do with the new electoral college allocation.
