If you truly believe that Romney has given up on Wisconsin, Michigan, and Pennsylvania then you are being silly. He is very competitive in all 3 states and will need to pick one or two off if he is to have a chance at the Presidency if he doesn't win Ohio. I think Florida is Romney's at this point along with North Carolina and Virginia. I think he wins those. Colodrado will be close but I think he ends up taking it as well.
Anyway, it should be interesting with the storm hitting the east coast. The likely GOP voters have the lead as far as enthusiasm goes. Should be interesting to see what happens. As for Wisconsin, I can see Romney actually winning that state. Walker won his recall and numerous recalls have turned out similar. Add in Wisconsin native Paul Ryan on the bottom of the ticket and you can see why a state Obama carried by I believe 14 points in 2008 is now a dead heat.
Actually you're being silly in this case. None of those three states are really in play. Of the three only Wisconsin is arguably competitive. To give you an idea as to how far out of the race Romney is in those three states, sums of polls indicate that Romney is as far out of Michigan as Obama is out of Arizona.
We'll do this old-SAT analogy style.
Michigan is to Romney as Arizona is to Obama.
Pennsylvania is to Romney as Missouri is to Obama.
Wisconsin is to Romney as North Carolina is to Obama.
Virginia is a virtual tie. Considering you're saying you think Romney will win virtually every swing state that is competitive and some that are not competitive I'm pretty sure you're in pie-in-the sky fantasy land.
