Well, Obama is playing with his own experience. His population of voters are largely ghetto-ites. And they are not "stupid" as they vote their self-interest - for rewards for the indolent and improvident, the ghetto welfare constituency. What are there, some 37 million "poor" receiving approximately $67,000 a year for four people?
The stupidity will issue from the leftists, whose egos are massaged by their "inferiors," who look to them for sustenance. Obama knows how "stupid" they are.
In Pasadena, California during the heady days when "black power" was first asserted, groups of Los Angeles neighborhood nobodies, thugs, were quick to learn that going to the Quaker Meeting and yelling, cursing, and screaming, and being generally insulting, they could obtain large amounts of money from the Quakers.
This process had an evolution, and political shakedown is now a sophisticated process, practiced by Obama as a street agitator fomenting action based on racial animosity, demanding goodies from the general community for not engaging in disruptive violence.
No. Obama "knows" how stupid you all are. It's just a matter of how prevalent your stupidity is among those from whom benefits are extorted. You've demonstrated your "stupidity" repeatedly and over an extended period of time. Is the cow milked dry? Some people never learn. Lefties will kowtow and play and replay their roles.
