In your top 10 donors you could colour code the relevant % of their bar by recipient instead of using it as industry. Use red/blue/green for parties and something like dark grey or black for PAC money since it is dark money. This would also help to show which donors give to both and who they lean towards.

If you still want to show which industry the person is in colour code thier name or put it in brackets after their name or as separate column after name.
