Current polling, from reputable firms, only give Romney an edge in Florida, Missouri, and a scant one in North Carolina from that list of twelve. They are not enough.
Assuming that Romney can hold Colorado, it will come down to Pennsylvania, Wisconsin, Florida, Virginia, and Ohio. If he can take Florida, Romney will need to take either Pennsylvania or any two of Ohio, Virginia and Wisconisin. If I were a resident of any of these states, I wouldn’t watch television or listen to the radio between Labor Day and Election Day. Inundation is not too strong a term to describe what will happen in these states during that period of time.
These polls, by & large, are using 2008 turnout figures. Different world in 2012.
