A quick google search shows that there are massive differences in how willing different generations are to respond to surveys, especially relating to how they are delivered. 40% of gen-z will abandon a survey if they are asked for personally identifying information.
Another user in this thread mentioned that this particular survey was delivered by mail, which means that this was only able to reach people with a mailing address, who actually read non essential mail, and who are willing to respond to this survey.
So do you have any evidence to imply that willingness to respond to a survey has anything to do with political orientation?
