Not happening, unless those Liberal/Marxist/Democrats in S. Florida jam the ballot boxes again.
Also recall that the the Omaha CD is off the table along with 6 votes from reapportionment. Also recall that a tie will win in 2012 whereas it would have lost in 2008. That basically cuts obamao's margin by over a third -- from 96.5 down to 62.5.
Note that almost half of the remaining margin is represented by Florida's 29 votes.
