Well, they are products of the public school system. IMHO the two most long term destructive changes in my lifetime were the institution of teachers unions in schools, with the right to strike, and the requirement that teachers must have a special degree in eduction to teach. That ensured that schools would be run by overwhelmingly female teachers, who studied little but the latest liberal theories about eduction, and were generally lowest scoring students themselves. Most of the problems we see now go back to those two changes.
Here’s an explanation from the Patriot Post. Makes sense to me.
Leftists politicos tend to be chronic overachievers because they have suffered significant loss — often the result of the disconnect with their earthly fathers. They subscribe to rigid doctrines and “nanny state” regimes to satiate their persistent insecurity, the result of low self-esteem and arrested emotional development associated, predominantly, with fatherless households or critically dysfunctional families in which they were not adequately affirmed.
Obama manifests all of these characteristics, and clinically speaking, there is a diagnosis. Leftists are pathological case studies of Narcissistic Personality Disorder, as outlined in the Diagnostic and Statistical Manual of Mental Disorders — the standard reference used for psychiatric evaluation.
Of course, there are many conservatives who were raised by a single parent or in critically dysfunctional or impoverished homes. However, somewhere along the way, they were lifted out of their misery by the grace of God — often in the form of a significant mentor who modeled individual responsibility and character. As a result, they have the courage to internalize their locus of responsibility.
Leftists, on the other hand, externalize responsibility for problems and solutions by holding others to blame for their ills, and by bestowing upon the state the duty for arbitrating proper conduct — even proper thought.
A footnote: It’s no coincidence that conservative political bases tend to be suburban or rural, while liberal political bases tend to be urban. The social, cultural and economic blight in many urban settings are Leftist breeding grounds for legions of the disenfranchised, those who are largely dependent on the state for all manner of their welfare, protection and sustenance.
These legions identify with Barack Obama. That is the substance, the essence of Obama.
