What they can't screw with is the demographic sampling, and Obama is losing every category compared to 08. That, coupled with the enthusiasm gap, voter registration trends and lack of "hope & change" feelings, is serious trouble for Team O. That being said, there is NOTHING they have not thought of, and will do EVERYTHING to maintain their administration.
The debates have only proved that Obama can't run on likability so, the most dangerous time of the campaign season is now, and R2 had better be ready for it, or get out in front of it.
