“If you’d like to inquire about participation, you can do so by contacting us through email. We are looking to expand our panel with those who are willing to conduct repeat interviews, are of age, eligible to vote and are qualified via a screening questionnaire. Include contact information, as well as zip code and/or city and state.”
It does not appear they utilize the scientific methodology of Random Sample.
I’m more concerned with the trend rather than the absolutely percentages.
How quaint!
