Create a map that you think is a possibilty for 2012.
Only one request. Put the electoral votes on what that map is for 2008 and for 2012 and who wins.
If you divide the country into red state blue state the Republicans have the advantage in 2012, but if you divide it into red state blue state swing state the situation changes.
For example consider the following which represents a narrow win in 2008 and 2012 for the Democrat, and involves a Dem victory in Arizona and Nevada:
274-264 in '08 and perhaps 271-267 in '12
