The structure of the Democrat Party is such that it is "born to lose." How did this come about? Well, their strategy was to create special interest groups beholden to them for enactment of their programs. It worked for awhile. Then the extremist special interest groups became more demanding.
For example, a core constituency of the Democrat Party was labor. There were other constituencies. Blacks. Homosexuals. Feminists. Abortion supporters. Anti-war proponents.
The party operated along the lines of a vector with pulls of varying strengths in different directions, which resolved themselves in election of Democrat candidates.
But as the dialectic forces operated, this heterogenous group displayed antagonisms between interests within the party. Man does not live by bread alone. Other factors alienated members of labor as their values were offended by the advance of extremist agendas.
The black constituency had demands. The euphemistically named "affirmative action" programs discriminated against members of labor, many of whom were marginal and whose entry into various aspects of activity deferred to inclusion of affirmative action beneficiaries - in school admissions, job opportunities (freezes on fire department non-black promotions by the courts, etc.), and other "remedies" in other areas.
School busing was also an outgrowth of black activism. Working class families found their children transported for as long as two hours per day, and their well-being compromised to accommodate black initiatives and interests.
Voila. There was antagonism between the labor and black groups. Democrat affiliates, whose association was based on labor membership, saw their perceived interests surrendered by the party to the interests of blacks.
The same process occurred in relation to shrill extremist demands by other constituencies. Some labor affiliates are offended by the idea of so-called "gay marriage." Others are offended by support of killing of infants going so far as with Obama, supporting abandonment to death of vulnerable survivors of attempts to kill them by abortion. Many are offended by late-term abortion, or abortion itself after conception. Many members of other groups are supporters of American exceptionalism and oppose abandonment of military efforts in which America "loses."
There are members in each special interest category also put off by advancing the interests of others.
The alliance held together a long time. But that was yesterday, and yesterday is gone. Obama is symbolic of support for all of the programs that many Americans find offensive, violations of their core values. He accentuates the idea of black preference by his decades long membership in black liberation theology hate-mongering organizations dissing "america" and "whitey," together with his affiliations with hate-America, abandon the conflict domestic terrorist Bill Ayers and his ilk. Obama supports abortion all the way to include infanticide of the most vulnerable among us. Obama embraces the idea of "gay marriage." Why continue? The disintegration of the Democrat Party was inevitable as the forces of the dialectic took hold. Ask Hegel. Ask Marx.
But what are Democrats to do? They are beholden to blacks, who constitute some 28% of their constituency. Reformation will be a difficult enterprise. The presence of such a large group with demands for special interests prevents the formation of a labor type coalition that exists in many European countries, a coaltion that focuses on health care, and other social issues, rather than being constantly preoccupied with race.
