Submit button for poll response

Currently it is not very obvious to an end-user that a poll response has been submitted. There is a small "Autosaved" message that appears but that is easily missed and it doesn't communicate that the response has been submitted since it could just be referring to their work in progress being saved. When a user submits a new idea via the feedback widget, they get an "Idea submitted" message so the same thing would be helpful here.
