Politics and sports are not analogous. Political ideology is quite different from this situation. The Wells report deal is exclusively a matter of critical thought and objectivity, something many people lack.
One can be objective and think critically, and come to entirely different conclusions than you with regard to how the country should be run. I don't think anyone can be objective and think in a critical, rational manner and come to the conclusion that the Wells report was presented fairly and with a balanced, objective tone.
It's unfair to imply that those who supported Obama in his pursuit of a second-term "aren't very bright". There was another candidate, previous experience(s) with former presidents, the idea that politics moves slowly, etc, etc. Many variables in place. I'd have a hard time generalizing any group of voters/supporters as 'x' or 'y'. It cannot be done. You have to talk to each individual and figure out why they supported a particular candidate in order to get an idea of what they were thinking and why they voted for the person in question.
