One of things I love about Russian History and the great Russian novels, is this idea that nobles and the commoners spoke different languages. The nobility was not just different in terms of economic life, the nobility of Russia inhabited a completely different cultural and social and linguistic universe then did the common people. The GOP in 2015 is like Russian circa 1900.
From the mid 1960's to the mid 1970's the GOP became the party of the rich and the racist. They were able to bind cultural conservationism and white resentment with moneyed interests. For a while, this coalition was quite cohesive and successful.
Up through the early 80's, the rich and the commoners attended the same churches. The rich went to college, the working class aspired to see their children go to college. Unionization raised the lot of working class whites while high marginal tax rates and a regulated financial services sector insured that most rich people never became super rich. There were middle class and upper middle class Republicans who could act as a bridge between the money and the masses.
Today, the middle class has been gutted. Deregulation and deunionization have amplified the difference between the rich and the poor. Poor Republicans go to evangelical churches, rich Republicans are atheists who might pay an occasional holiday visit to their Episcopal church. Republican donors send their kids to liberal arts colleges and Law School. Working class Republicans, believe that higher education is inherently subversive. GOP elites take George Will, Tom Friedman and Fareed Zakaria seriously, Republican voters like Rush Limbaugh and Alex Jones and the 700 Club. GOP voters use short and declarative sentences, GOP elites engage in elaborate acts of circumlocution. Today, most donor class Republicans live on the Coasts, downtown and in posh zip codes. GOP voters live in Middle America, in the exoburbs and in poorer rural places. GOP voters genuinely fear abortion and gay marriage, GOP donors have gay sons and their daughters get abortions.
Despite this schism, the GOP has done fairly well in recent elections, particularly mid term elections. However, the schism is very real and the cultural and economic gaps are just waiting to be exploited. Trump may be a Democratic plant, a rank opportunist or a man who is earnestly seeking the GOP nomination but what is clear is that he is ruthlessly exploiting the gap that exists between Republican commoners and Republican elites. Trump sees Bush's staid comportment, Rand Paul's theoretical Libertarianism, John Kasich's tenure at Lehman, Lindsey Graham's tepid defense of immigrants and Rick Perry's sad attempt at being an intellectual ad he ruthlessly pounces. To cap it all off, he disguises his shrewd attacks as spontaneous truth telling.
Like early 20th Century Russia, the GOP is a big, brutish hegemon that can still throw it weight around. Also like late Czarist Russia, the GOP is so internally divided that it relative might can dissolve rather quickly if someone can articulate and exploit the divisions between it people and it rulers. Donald Trump appears to be Lenin in 1917 on a fateful, East bound train.
