To the opening poster: Your question is tautological (or, perhaps, a clever play on words). A better question would be, what does it take for a US president to be good for the Jews.
Here are some things that are not good for the Jews:
1. Stirring up anti-Semites and making them think they have the support of the US president.
2. Alienating US allies.
3. A do-nothing response to a pandemic that sickens Jews, and others, and weakens the US economy.
4. Encouraging an armed assault on the US Capitol.
5. Attempting to overthrow the results of a US election.
