Describe a secular Jewish Republican

[RFayette 🇻🇦]

My general impression is that they seem to be very fiscally conservative and hawkish re:Israel.

This.  I think Mark Levin and Michael Savage fit the bill quite well for *strongly conservative* secular Jewish Republicans, in contrast to someone like Ben Shapiro or Dennis Prager for more religious Jewish Republicans.   I think someone who is Bloombergesque describes many of the more moderate secular Jewish Republicans, but they were very anti-Trump and probably don't even ID as Republicans overall.
