by continuing to lie compulsively, by disparaging the press and the first amendment, by attacking allies and sidling up to strongmen, by going to international meetings unprepared, by continuing to blame Obama and Hilary for everything and not taking responsibility for anything, by turning a blind eye to racists, by using politics of division instead of uniting, by not enacting sane gun control, by being fiscally irresponsible and increasing the debt and deficit by unsustainable amount in order to give tax breaks to millionaires and billionaires, by invoking every trick to go around congress and senate, by not standing up to Putin and potentially having colluded with him, by continuing to obstruct the investigation into Russian interference and to not take steps to prevent it in the future, by ignoring the constitution and the emoluments clause...there is more, that's just a first pass at the top of my head.
