Well, apparently Romney is set to be campaigning in PA, MN and WI in the last few days.
As far as I can tell that has 3 possible meanings
1. Romney thinks Ohio or Virginia is a lost cause.
2. Romney thinks Ohio and Virginia are in the bag and wants to get a bigger majority.
3. Romney isn't certain either way on Ohio and Virginia but feels more campaigning there won't achieve anything.
Personally I think it's a bit sad that Romney (a man too weak to stand up to the looneys who think Obama is a Muslim) has a better shot of winning than McCain (who wasn't).
