@realcaseyrollins I won't leave voicemails. I'll speak to staffers, or write letters.
I think it's part of the job description of a Senator to accept feedback and petitions from his constituents.
I don't know I have any way to enforce that, other than vote against and try to persuade others to vote against him, but yes, I think it is part of his democratic role to receive them, and for at least his office to read them and take constituent concerns into account.
