On Face the Nation this Sunday, I attempted to explain the 2016 cycle in 40 seconds. Pull back from the close ups on Donald J. Trump’s tweets, and the political realignment we are experiencing becomes obvious and impossible to ignore. The post-Cold War left-right politics of the nation have been breaking down in slow motion for two decades. They are now being replaced by a different type of inside-outside politics.

The Trump phenomenon is neither a disease nor a symptom – he is instead the beta-test of a cure that the American people are trying out. It won’t work. But this is where our politics are going: working and middle class Americans are reasserting themselves against a political and cultural establishment that has become completely discredited over time and due to their own actions.

Of course, as one more sign of how weak the establishment is, elected Republicans are the last people in the world to understand what’s going on. “While still hopeful that Mr. Rubio might prevail, Mr. McConnell has begun preparing senators for the prospect of a Trump nomination, assuring them that, if it threatened to harm them in the general election, they could run negative ads about Mr. Trump to create space between him and Republican senators seeking re-election.
