This isn’t unique to the frum.
Pretty much all non-Islamic religious groups strongly support Trump nd the Republicans.
Even the Amish who don’t vote unless they feel threatened by a candidate supported Trump.
It’s not really Trump support as much as the recognition that the Democrats are becoming increasingly hostile to religion so it is of prime importance to have Republicans in office.
The Muslims are the exception because liberal beliefs require making an exception to their general view of religion and respecting Islam
