The obvious:
He's a member of the Republican Party.
He was born in June 14, 1946.
He became the 45th president in 2017 and will become the 47th president in 2025.
etc
Besides the obvious:
No idea.
Everyone's political beliefs are different because we might be a member of the Democratic Party with conservative beliefs, a member of the Republican Party with liberal beliefs, etc.
I wrote "political beliefs" in the title because "belief" is used in a religious connotation.
