We have rapidly moved from better than expected to worse, as the value of preserving or conserving the lessons of the past have been thrown over for the promise of clinging to a perception of total, permanent victory, which is not what this system was designed to produce in its electoral process.
What's different from 1973 is a clear perception by a large part of the electorate that this is a coup, and the inability of those in the media to perceive or process this. Rightly or wrongly this will cause damage. Neither side can cleanly overpower the other. The most likely outcome is a political Stalingrad. It will be epic -- epic disaster. Who is in charge of the clattering train? The axles creak, and the couplings strain. And signals flash through the night in vain. My theory is no one is in charge of the clattering train. Everyone is along for the ride assuming there's a driver in the cab.
Someone once said that PowerOfResistance = Will * Means. If either Will or Means go to 0, PowerofResistance likewise goes to 0. With Means so evenly balanced, it becomes an unproductive target. Both sides will must target Will to prevail. The will of one side or the other must break - the electorate's will to preserve their 2016 victory, or the establishment's will to preserve their vision for the future and validate their emetic reaction to the foreign infection in their midst that is the Trump administration. The establishment is playing for keeps here. Will the electorate do so as well, and if so, how?
Any stalemate will likely produce an unstable negotiated settlement or truce. Stalemate is not at all improbable. The chimera of total victory and permanent majority is destabilizing things. An institutionalized stalemate is electoral democracy. A permanent majority is a trainwreck that never ends.
