Phone suspected Spam... no message left... so annoying

Automated 'important' call message/survey for the voters of Cook asking to answer a few questions.
The first question was: "What is your gender? Male, female, or other? Press 1, 2, or 3."
i didn't answer the question and hung up.
Regardless where the call is coming from, considering the upcoming bi-election this call is inappropriate and to me it sounded like it may be 'canvassing'.
Do not answer any questions!
