On one level, it was moronic for the WashPost to try to literalize something that can hardly be analyzed on a literal level.
But in some ways Trump was too kind. Watergate involved a single-night burglary; email-gate involves 4-years' defiance of records retention defiance and a huge mishandling and exposure of classified information.
Nixon's cover-up, from the night of the burglary through his resignation lasted about two years; The cover-up on the part of The SHREW, BHO, the State Department, the DOJ, and the FBI has been going on for over 7 1/2 years, and is ongoing.
No matter how you define the full scope of Watergate, no one died as a result; we'll probably never know the full scope of the damage to the US The SHREW has caused, but the likelihood that multiple people have died as a result of The SHREW's mishandling of classified info is somewhere between very high and near certainty.
So as far as I'm concerned, the Hill-Shill WashPost can take their Four Pinocchios and shove them up their colluding @$$!
