There seems to be a growing number of Democratic politicians who are questioning the mental health of Donald Trump. Al Franken alleges that a few of his GOP colleagues share this concern. Bernie Sanders has described Trump as "delusional" and noted that he is a pathological liar.
When Franken was asked by Jake Tapper about this, about what he meant re: Trump's mental health, the only answer he gave was that Trump lies a lot. Similarly, your description of Sanders's comments above is fixated on Trump speaking untruths, and musing about whether he believes the untruths or not.
But I think that's only one piece of what people are talking about re: Trump's mental health. The bigger issue is the one described here:

AFAIK, there are no Democratic politicians who are going there in their attacks on Trump's character, and I wonder if that's ever going to change over the course of Trump's presidency. Is attacking a political opponent along these lines inevitably going to be painted as over the top by the media, even if it's true?
