This scenario is, as many have said, unlikely.
First, Virginia is pretty much a gimme for Romney at this point. Also, as one poster mentioned, it is highly unlikely that Romney would win Ohio AND lose VA. Of course, Romney might lose Oiho, not knowing where that state is located, and not having campaigned there. :>)
Colorado is also looking like a Romney winner - Drudge has him up by 4 there, and undecideds usually vote for the challenger.
Quite unsaid here is that Maine is almost certain to give Romney 1 EV. If the EV vote is as tight as mentioned in the map provided, that 1 vote will make the difference.
I also share the view that Obama won’t win the popular vote. He is down by 22% in the South, a Romney lead that is hard to overcome (especially with the Mountain West probably being just as lopsided in his favor).
However, the only real “nightmare scenario” is one in which Obama takes the oath of office on 1/20/2013. All others we can deal with, including nationwide rioting. Regarding the credibility of Congress, it is so low now that it really can’t go any lower, so who cares?
In order to mitigate the “riot factor”, Mitt needs to win decisively, and not surprisingly, either.
The 0zombas must go into election day with the clear understanding that their guy is not likely to win.
