Trump’s lies have a purpose. They are an assault on democracy.

When political actors can’t agree on basic facts and procedures, compromise and rule-bound argumentation are basically impossible; politics reverts back to its natural state as a raw power struggle in which the weak are dominated by the strong.
That’s where Donald Trump’s lies are taking us. By attacking the very notion of shared reality, the president-elect is making normal democratic politics impossible. When the truth is little more than an arbitrary personal decision, there is no common ground to be reached and no incentive to look for it.
