Wow! I thought I had been to a lot of states....
UPDATE: I have been giving this some thought. Obama has been to 57 states, not including Alaska & Hawaii. That makes for a total of 59 states.
To me it is obvious that this is the DNC's master plan to ensure Obama can win the Electoral College. Now they just need to find 9 new left leaning states, especially ones that take away Electoral votes from normally red states. So under the super-secret DNC plan, Miami, Denver, St Louis, Houston, San Antonio, Las Vegas, Cleveland, Philadephia, and Puerto Rico will become 'states', and be given the requisite number of electors based on the population taken away from their former state. Genius! It is too bad that Obama had to go and lose his bearings and reveal the whole plan!
(Looks like the esteemed Dean Barnett had a similar take)
