P1) Trump routinely lies (e.g. how many people showed up to his rallies, the fact that he went down in helicopter with Willie Brown, etc.). P2) If you routinely lie, then you do not value justice. P3) If you do not value justice, you should not be the POTUS. C) Therefore, Trump should not be the POTUS. Premises 1 and 3 seem undeniable. Premise 2 depends on the intuition that treating others fairly requires truth-telling/valuing the truth.
