curl -s --data '{"jsonrpc":"2.0", "method":"database_api.list_witness_votes", "params": {"start":["goodguy24",""], "limit":200, "order":"by_witness_account"}, "id":1}' https://api.steemit.com

I assume you are familiar with this api call, but if not I thought maybe it couldn't hurt to bring it to your attention. It appears that this calls up to 200 users who voted for goodguy24. I trust you know how to change the usernames and the limit (max 1000).

It starts with goodguy24, then it moves on to the next witness in alphabetical order-which could be a good or neutral witness. But I am sure you know how to tokenize the data: in this case ["witness":"goodguy24"] .

I am not sure what language you use, but here a php array. May want to double check it.
