Can you donate to AI advocacy

I posted this question on LessWrong, and one commenter suggested this forum, so I'm asking here as well.

Unlike other charitable causes, AI Safety affects affluent people, which suggests to me that advocacy may be more effective than direct funding of alignment research.  Originally, the donation options I found all seemed to be for funding research.  My question is: Is there a way to donate to AI advocacy efforts?  

I'm also ok donating to organizations or grantmakers that explicitly consider funding advocacy efforts.  And feel free to make a case for why a specific donation avenue is most effective, or to let me know if I'm missing something like a clear reason why advocacy can't be bought or won't be effective.
