The percentage of physicians accepting new patients did not vary significantly between 2005 and 2008, ranging from 94.2% to 95.3%. Physician acceptance of new Medicare patients dropped from 95.5% in 2005 to 92.9% in 2008 (P= .01) (Figure). Physicians in private practice were largely responsible for the declining acceptance of Medicare patients as determined in stratified analyses (95.5% in 2005 vs 93.0% in 2008;P= .01) (eTable; http://www.archinternmed.com).

There was a more pronounced decline in physician acceptance of patients with private noncapitated insurance (93.3% in 2005 vs 87.8% in 2008;P.001). A smaller percentage of adult primary care physicians accepted private noncapitated patients over the study period (97.3% in 2005 vs 89.9% in 2008;P.001).

Rates of acceptance of new Medicaid and private capitated patients were lower than Medicare and private non-capitated insurance, but also showed a decline over the study period. Acceptance of self-paying patients was more than 96% in all years and did not change significantly
over the study period.

You are partly right, in that many low information voters do vote according to their emotions and their gut impressions of candidates.

And Obama wins that crowd by a landslide. Because most of those people personally like Obama while they can't stand Romney...
