"The Fish Rots from the Head"

"Well, our system depends upon something like a consensus, something like majority rule. But now we have a president who outright lies about... everything. He lies about the number of votes he received, about the size of his inauguration crowd, about his own achievements, about Muslims cheering in the streets after 9/11, and so on. He lies about basic observable facts.
"I think the cumulative effect of all this lying is to make people deeply cynical about out entire system, and that's very corrupting."
