One thing you can almost say, the Democratic Party is Toast, going away like the Whigs. With the Democrats at the lowest point in electoral strength since the Reconstruction era of the late 1880's, now the House Intelligence Committee can give Trey Gowdy some real work to do as he interrogates dingbat Dr. Evalyn Farkas (who blabs out everything last week on MSNBC), and Susan Rice, to find all of their 'associates' as Farkas says, that were intentionally leaking sensitive or classified information. The WaterGate hearings went on about a year and a half I think, totally wrecked the Republican party, can you imagine what an even bigger scandal involving far greater numbers of players (Not just a few 'plumbers') will do to the already historically weak Democrats? They're Gone.
When I was a VERY young person in the 1960's, I remember well a bunch of very grumpy, bitter older individuals who still after many years were angry about the Presidency of Franklin Delano Roosevelt, believing he had given too much away. I suspect the results of this crisis will be a similar bunch of cranky old Liberals, never getting over the changes wrought by Donald J. Trump in preventing full bore Socialism/Communism from taking over the Republic.
