That TNS poll has a weirdly high number of undecideds compared with other recent polls: the full figures are No 39 Yes 38 Don't Know 23.
Perhaps their methodology is different? They might state that you have 3 options as anwers (Yes/No/Don't Know), while the other pollsters don't mention the
don't know option before asking. Or the other pollsters might ask again for a clear yes or no if one initially answers with a
don't know.
Or maybe they just group
don't know and
won't vote together? I can't check the study though at the moment. The page doesn't load for me.
