Also interesting.
I looked for records from 2015-2016. Cross reference occupation "Attorney" (I know, I am missing occupation "Lawyer" and such).
About 19K individual "Attorneys" contributions to the Trump campaign (total). Many did multiples so figure 6K. 447 from my state of PA (so figure about 150 individual people).
Run the same for Hillary. JUST "Attorney" (not "Lawyer") and JUST PENNSYLVANIA ALONE seems to be 6K listings: https://www.fec.gov/data/receipts/individual-contributions/?two_year_transaction_period=2016&min_date=01%2F01%2F2015&max_date=12%2F31%2F2016&contributor_occupation=attorney&committee_id=C00358895&committee_id=C00431569&committee_id=C00575795&committee_id=C00586537&contributor_state=PA
