If you go to real clear politics link and click on each battleground state...you will see Mason Dixon has Obama at 47 or less in all the BG states except Colorado...and that is at 49 percent. IF Obama gets no more percent than he polls he is in trouble and McCain will win the election...
That is assuming Mason Dixon is accurate AND Obama doesn’t do better than he polls.
More likely to do worse, not better.
