Uhmm...why has O had to make campaign stops in Wisconsin and why would Gov.Romney waste time and money there and in Pa if his internals said it was hopeless?
This particular re-election campaign is surely much different from others in the past.
After someone wins the presidency the first time, when the second time comes around, one tries to expand, build on, the margin of victory that had gotten one into office. One wants to get a bigger victory the second time.
I offer the examples of Eisenhower 1952-1956, Nixon 1968-1972, Reagan 1980-1984, and the second Bush 2000-2004, in which these candidates sought, and got, votes they hadn't gotten the first time around. These are extreme examples, as
every president seeking re-election has done this (but with less stellar results).
Excepting this incumbent.
I'd fully expected Barack Milhous to be campaigning for a second term in places such as South Carolina, Nebraska, or Idaho, to pick up votes that had gone to McCain in 2008, but oddly he hasn't, instead reploughing old territory he'd already won his first time around--Wisconsin, Ohio, Pennsylvania, Florida, &c., &c., &c.
One wonders why.
Or, really, seriously, one already knows why.
