About 46% for the President and 45% for his opponent.
Baring some unforeseen event, that is pretty much going to hold steady.
The elections is in the hands of 9% of the voters who are undecided.
One can produce the most positive rose-colored ad for your favorite candidate and his opponents will not be swayed. Likewise, the most negative ominous ad, outrageous or factual, will not sway the supporter away from his/her support.
Nonetheless, I do hope there will be some positive ads along the way so the undecided voter doesn't base her/his choice exclusively on fear or disdain.
