To paraphrase the GEICO commercials: "DEMS lie: it's what they do!"
Given the amoral nature of the entire DEM Party and especially of their candidates, Lies are never an issue. Truth does not exist: DEMS create "Truth" for their purposes, and if their "Truth" contradicts Real Truth, then they yell it ouder and repeat it endlessly. If their Fake Truth begins to falter, it goes down the memory hole, and they move on and create a new Fake Truth.
