Rasmussen Reports, one of the more reliable public pollsters, proposed there is a [somewhat tenuous] connection between a person's education level and the person's approval of Obama.
"Recent Rasmussen Reports national telephone surveying of Likely U.S. Voters finds that 57% of those who attended high school but did not graduate at least somewhat approve of the job the president is doing." The undereducated are more likely to approve of Obama.
"Similarly, 56% of voters who attended graduate school approve of Obama’s performance." The highly educated are more likely to approve of Obama. Examples of highly educated are lawyers, community organizers and politicians, who make their living off the people's taxes.
The vast middle, suffering shrinking under Obama's administration, is not very interested in Obama's continued dominance. Rank and file workers, like Joe the Plumber, see Obama-style governance as useless. Incidentally, Joe the Plumber is running for Congress from Ohio's Ninth District.
The vast middle class has the plumbers. Not many high school drop-outs would qualify as plumbers. No college level academics would stoop to plumbing. But if the drains back up, we all sicken with cholera. Obama and his followers must remember they need us all.
