It's worth observing that Republicans lean toward professions that don't need a whole lot of people. (Truck drivers, Pilots, Surgeons, Farmers, Finance etc.)
Democrats lean toward professions that cater to a larger audience. (Performance, arts, professors, flight attendants etc.)
One shocking thing for me is that donations from Pastors, Reverend, Minister and Priests lean democratic.
For pastors and reverends, probably a high percentage are African-American while for priests many are Hispanic although white Catholics tend to be more competitive than white Protestants. Amongst white pastors, reverends, and ministers, I suspect Trump got over 70%. Likewise amongst non-Hispanic white priests, pretty sure Trump won too.
