Knowledge of socio-political character is essential to understand and prevent the destructiveness in American politics.
The two paty system in America functioned in the past authoritarian social order to maintain a balance of power between the opposing ideological forces of the left and right. It began to disintegrate around 1960 accompanying the anti-authoritarian transformation of society. This resulted in the political mainstream in the entire nation to shift leftward. The Democratic Party became infiltrated by politicians from the extreme left.They were pseudo-liberal/communist characters who took over that party. This produced an imbalance between the opposing forces of the left and right and the two party system was destroyed.
The shift to the left in the American mainstream is responsible for how a full-fledged communist masquerading as a bona-fide liberal character was able to win the American presidential elections in 2008 and 2012. It also explains how two of the least qualified candidates were chosen by the ever-clueless public to be their president. One is a leftist extremist with psychopathic, criminal tendencies; the other is an individual with poor impulse control and questionable good judgement. Both are populist candidates catering to the whims of “the people.”
Once again, the emotional plague is victorious as American politics has lost any semblance of rationality. Americans can now look forward to an even sicker, multiparty, european-style political system in future elections.
