"You're in charge of communications for a congressional campaign. Your candidate is frugal, perhaps to a fault, and doesn't want to spend a penny of the hard-won dollars he gained by working the phones. You need a poll, but he doesn't want to pay for one.
"There's a local state Senate candidate who's getting ready to go into the field. Granted, the state Senate district isn't an exact match for the congressional district, but it's about 2/3 of the same territory, so, if you squint and tilt your head just so, you might be able to think you see results that would be somewhere near the ballpark of a real poll.
"So you piggyback on the local state Senate candidate's poll -- you buy a couple of questions. And it shows that, in that part of the congressional district that overlaps with the state senate district, you're competitive with the congressman you're challenging.
"Now, here's the question -- now that you've got this data back, a) is it useful to you at all, b) if so, how? and c) would you ever, in a million years, release it to the public as evidence that you're competitive with the congressman you're challenging, without acknowledging right up front that the data is based on a survey sample that was compiled for someone else's survey, and that it doesn't include all portions of the congressional district?
