1. That the Democratic Party is in such a crisis (not since ’68 have I seen anything like conflict so bitter) at the same time as the Republican Party is ripping itself apart, is not an accident. It is a product of wide-spread perception, and accurate perception in my opinion, that there are problems that the capitalist parties simply cannot solve.
2. There is no question that the Sanders campaign has pulled in large numbers of people who had not previously been involved in party politics. They perceive that the forces (ie, Wall Street) that have caused most of the problems in their lives are the same forces, personified by Clinton, that are preventing them from having a voice.
3. The “liberal elite” (the upper middle class and white collar urban liberal) that has been the foundation of the Democratic Party for the last two generations, with its focus on identity politics and its open disdain for the worker, is directly clashing with the those forces that are still trapped in the idea of party politics but are angry that the Democratic Party has nothing to say to the millions of poor and working class people whose lives have been shattered by capitalism.
4. I doubt there is a single billionaire, a single Wall Street banker, a single oil executive, a single Washington power broker or politician, a single media mogule, a single Halliburtan executive, a single general, who is pleased about how furious people are at the two parties. None of them are happy about the general hatred of both Trump and Clinton, at seeing the Democrats squabbling like unruly fourth graders while the Republicans stare at Trump like a smallpox patient looks into a mirror trying to convince himself it doesn’t look so bad after all. And if they don’t like it, and they can’t fix it, that indicates the problem is the capitalist system itself, not who happens to be running it at any given moment.
5. The mutual frustration and hostility between Clinton and Sanders supporters can be reduced to one group that wants business as usual under conditions where business as usual is a dead-end, and another group that wants to change the Democratic Party into something that it is fundamentally incapable of being.
6. Bottom line: Both political parties are in crisis because the ruling elite are in crisis about what to do about the tremendous anger and resentment directed at the out-of-control juggernaut called American capitalism.
