Fifty–fifty vision: the pollsters’ preference problem
- Analysis for Inside Story, by Swinburne Adjunct Research Fellow Peter Brent
What to make of today’s Newspoll, which has the parties level after preferences at 50 per cent each? It follows a closer-than-usual 52–48Ipsos poll in Fairfax papers last week and a general narrowing since late last year.
Newspoll has already rippled around ABC radio and the rest of the media.
