Probably a higher proportion of the people out here care about privacy, because they're unlisted or they don't even have a landline. So undercoverage, it probably introduced bias, and it implies that 42% is an under, underestimate of the percentage of the senator's constituents who care about internet privacy. Now the last question, volunteer response sampling. Well, this would be the case where you, you know, the senator, I don't know, put a billboard out or just told someone, told a bunch of people, maybe on her website, hey, vote for this, or give us your information on how much you care about internet privacy. And that would have been, the source of bias there is, well, who shows up on that website? Once again, if you did, hey, come to my website and fill it out, you're filling, you're only getting information from a subset of your population who are choosing, who are volunteering. That is not the situation that she did over here.
