I'm sure Trump tells the truth sometimes. But nowadays the strategy, where it is applicable, is to tell the lie, make it big, and keep telling it, and then tell it again. Never back off the lie. Just lie and lie and lie and lie. And don't feel bad about it. Then lie some more. Etc. And keep the data secret.

The media environment on the local and national level encourages this. Local papers dying off, less resources to dedicate to investigative work. And no resources to spend on local commentary of national issues.

Works to the advantage of the Trump=Mansourian Complex.
