There were 1623 humans in total with at least one person identifying as one of four political parties (but the number of each w,x,y,z is unknown). My guess is these were landline phone calls to homes during the day as it's Newspoll, so not really an accurate sample of the population.

Question: The federal government plans to introduce a two-year trial
in which unemployed people newly claiming newstart allowance and youth
allowance could be required to undergo a drug test. Those who test
positive would be put on an income management program with 20 per cent
of their welfare paid on cash and the rest paid through a debit card.
Are your in favour or opposed to this trial?
