Hello Dave,

Welcome to the list!  Thanks for filling us in on this information.

It would seem, then, that the pollsters didn't tell the
participant about the "unsusual aspects" portion of the poll in
advance.  In that case, the difference between 6000 and 5947 may
indeed be indicative of the number who declined to participate
further after this section of the poll was reached.  In that
case, however, the possible bias I was concerned about would
indeed be negligible.

I do notice that for some of the Report's questions there were
5946 responses obtained, and for others 5948, so I suppose they
did have to accept some responses that overlooked answering a
question, or where the respondent wasn't sure of which of two
categories to place the answer in, etc.
