You wrote that "No one doubts President Obama's formidable intellect." Many people doubt that is the case. The reason is that they understand there are only two possibilities; either Obama is a moron or a monster. If he doesn't understand how his actions are ruining the country, he is a moron and, if he understands how his actions are ruining the country, he is a monster. And being unwilling to believe we actually have a president who is a monster, they choose to believe he is a moron.
