If you have audacity to compare a President to Haman, surely it will be someone who would either get cash from Persians, or send cash to Persians, and who hated a Jewish leader (mishevet) Binyamin for no particular reason except tha B did not bow to his will …
as to Trump, I would compare him to Yiftach – not respected, prideful, but is able to accomplish what more polished leaders could not. On a less serious side – both Yiftach and Trump:
reject land for peace; are disparaged by relatives; have outlaws around him; fight internal enemies; make and insist on random promises; boast about his houses; love their Jewish daughter
