Looks like a banzai charge coming up.

That poses dangers of its own. A healthy two party system that can settle on an acceptable center is a pretty good formula for stability. If the Democratic Party starts a Banzai, the act of self-destruction will be an inflection point in itself. Because rather than drifting back to the center it could possibly be driven even further left. History has examples of leftist movements in which each successive setback makes it all the more so. They wind up going on their Long March to Yenan like Mao and coming back twice as ferocious as before. In the end they either win it all or lose it all. That would be unhealthy for two-party politics.

As for the Republicans, it’s hard to say what they may turn into in a sharp clash. About all that can be safely said is that if President Obama really embarks on a Banzai charge the variance of the outcomes will increase dramatically. We don’t know what will happen. We only know that things become more unpredictable.
