'' is it too much to think that if Trump had any real arguments he wouldn't need to lie?''
yes, it is too much to think such
you are talking about a pathological liar
a pathological liar HAS to lie - even when telling the truth can suit their benefit - they MUST lie - they are driven to it
pathological liars aren't the mystery -------- what is more mysterious is that so many people can just put it aside and accept them AND believe what they are saying --
