Ghetto-dwellers tend not to vote in midterm elections. I have a bad feeling they’ll be fired up to vote for Prezzy.
And, don't forget, every state has been purging voter rolls like crazy. The number I read was 800,000 Dems to only 74,000 Rs. That's a pretty significant #.
Consider this: the difference in OH, NC, PA, and FL between Obama and McCain was just over 1,113,000. Subtract 716,000 from that, and you have THREE STATES swing R on that basis alone and still have 150,000 left over to cut into PA!!!!!!
