The American body politic⎯quiescent, even oblivious in normal times⎯is restless and fearful due to economic uncertainty. In its currently aroused state, it has become prey to cynical self-interested forces. When people are angry, they are easily led.
For example, if it is a tenet of faith of one particular group that climate change is a myth, it makes sense that shadowy petrochemical plutocrats, who have so much to lose from environmental regulation, would give behind-the-scenes financial support, through patriotic-sounding front organizations, to candidates who espouse a laissez-faire regulatory philosophy (To the big money backers, all that Libertarian stuff about individual rights and Second Amendment gospel are window dressing. Being billionaires, they can simply buy all the rights they want).
Their shills in the media and in politics, all of whom have so much to gain, willingly spread the party line (As Deep Throat said, “Follow the money”). Their legions of listeners hunger for easy answers, which are cheerfully supplied in large helpings.
In the final days before the midterm elections, President Obama is playing catch-up, campaigning hither and yon to defend and explain his vision for the country. He and his party might not be in such a jam today if they had taken the trouble to do the plodding grunt-work of repetitive indoctrination from the beginning.
His opponents certainly did.
