Obviously they are not identical, since no two people are the same, but the similarities are striking. Consider the following:
He serves his own power and isn’t really loyal to “Rome.” #TrumpisHerod
Herod Antipater was exiled near the end of his life after playing a political game during a Roman succession struggle. Trump has systematically used an appearance of near jingoistic patriotism as a tool to increase his own power. He did this before, during, and after his campaign for president.
He panders to power hungry religious conservatives. #TrumpisHerod
Herod used the Sadducees (a group of theologically conservative power brokers) to establish and bolster his power base among the people he governed despite the fact that he did not follow the moral or religious dictates of their theology. Religious conservatives make up a central part of Trump’s base and he panders to them by offering them power and a cultural prestige they have not recently enjoyed.
He is creepily obsessed with the sexuality of his own female relatives. #TrumpisHerod
Herod married his brother’s wife, who was also his own niece. Trump has made quite a few really disturbing comments about his daughter and her sexuality.
He is terrified that people will think he is weak; also he is weak. #TrumpisHerod
Herod imprisoned John the Baptist for speaking out against his marriage but actually found the prophet rather compelling in general. He was manipulated into beheading John the Baptist when he made a promise to his step-daughter which he then felt compelled to keep for fear that the people around him would think he was weak if he didn’t carry through on her request for the head of John. Trump seems to be almost viscerally motivated by the need to appear strong, but his inability to shrug off criticism and insult belie the fundamental weakness of his character.
His father was a builder, he built some things too. He thinks that makes him special. #TrumpisHerod
Herod’s father (also Herod) initially gained favor with the local conservative religious power brokers by restoring the Temple in Jerusalem. Having seen the public prestige that had granted his father, Herod Antipater also undertook several building projects in order to secure prestige and respect (though he ended up having to scramble and “patch” some of these attempts which his ignorance of the public’s actual religious positions undermined some of his projects). Trump’s basic boast is that he builds big things.
Herod built a wall (at Beth Haran); Trump thinks building a wall will make him great. #TrumpisHerod
One of Herod’s signature building projects was a new defensive wall at Beth Haran. Trump rose to power promising to build a wall across the US’ southern border.
Trump has a problematic relationship with marriage but is given a pass by the religious conservatives of his day (because he gives them power). #TrumpisHerod
Herod’s marriage to his second wife (his niece who had been his brother’s wife) should have been a total scandal to the conservative religious establishment as it was a flagrant violation of their religious law. However thanks to the cozy relationship he had with them they turned a blind eye to it. In the end it was John the Baptist (a religious outsider who made the conservative establishment extremely uncomfortable) who called Herod out.
He has a really problematic relationship with Syria. #TrumpisHerod
Herod’s relationship with the governor of Syria (Vitellius) was complicated and he ended up having to try and force Vitellius to support him by going over his head. Even then Vitellius backed out of the aid as soon as he could manage it.
He is a misogynistic predator who boasts about the sexuality of underage girls. #TrumpisHerod
Herod infamously showed off his step daughter (apocryphally named Salome) by having her perform an erotic dance for the guests he was trying to impress. He was himself so impressed that he ended up promising her anything she asked for, which led to the John the Baptist debacle. Trump has spoken and acted in incredibly misogynistic and predatory ways throughout his career but particularly with regard to Miss Teen USA contestants.
Most of these facts about Herod Antipater are based on either the Biblical record or may be found in the relevant entry in the New World Encyclopedia (which drew largely on Josephus and Philo of Alexandria)
