51. The Ol' Gaslighter of Capitol Hill

from Wiki:

https://en.wikipedia.org/wiki/Gaslighting

Gaslighting or gas-lighting is a form of manipulation through persistent denial, misdirection, contradiction, and lying in an attempt to destabilize and delegitimize a target. Its intent is to sow seeds of doubt in the targets, hoping to make them question their own memory, perception, and sanity. Instances may range from the denial by an abuser that previous abusive incidents ever occurred up to the staging of bizarre events by the abuser with the intention of disorienting the victim. The term owes its origin to Gas Light, a 1938 play and 1944 film, and has been used in clinical and research literature.

Not intended to disparage the old song "The Old Lamplighter."
