Trump’s tweets are some of the best, unfiltered information on his mental state. They are reactions to real-life situations in real time, over an extended span of time. Their growing frequency is an alarming sign, with an astonishing 52 tweets over 34 hours recently. Their content has also become more vitriolic.
Trump’s rallies are also very revealing. They are events he insists on doing, often against advice, and the adulation of crowds seems to ease, at least temporarily, an insatiable emotional need. These, too, have been increasingly more vicious in attacks against Hillary Clinton or John McCain, indicating that neither defeat nor death can satisfy the envy for what he may believe he could never have.
Trump’s rhetoric has been growing more violent. Attacking others seems to be a chief mode of coping for him; his accusation of “Democrats” behind Robert Mueller’s team as being “all killers” and his calling on “the police,” “the military,” and “the Bikers for Trump” to get tougher, appear to indicate that the stress of the presidency is getting to him.
