Another Civil War

Rather than open fire on a military installation, the conservative strategy in the current civil war is to first shut down Congress and then the federal government. That's what happened with gun control background checks: 45 Senators, mostly conservatives, refused to let the legislation come up for a vote. The same intransigence will kill immigration reform in the House of Representatives. In the fall there will be a total shutdown when conservatives block raising the debt-limit ceiling.

As Robert Reich recently pointed out, shutting down Congress moves the locus of legislative action to the states.

This means many blue states are moving further left, while red states are heading rightward. In effect, America is splitting apart without going through all the trouble of a civil war.
