What proportion of Australian voters regularly attend church and identify as Labor voters? How many of those are social conservatives in the mould of, say, Joe de Bruyn? If I’ve interpreted this piece by Crikey’s Pollbludger correctly, the answer to the first question is about 4 per cent. The relevant bits
This is partly reflected by the long-term decline in religious observance, with the proportion of respondents who attended services at least once a month falling from 23% in 1990 to 17% last year.
Of still greater interest is a pattern over the past decade in which the observant have grown more pronounced in their identification with the Coalition rather than Labor, with the gap reaching a new peak of 52% to 25% in the 2016 survey.
25 per cent of 17 per cent is 4.25 per cent.
Turning to the second question, I’d be surprised if socially progressive observant Christians (and members of other religious) didn’t account for 5 per cent of the total population of Australia. So, if Labor gets the support of half of those, that would leave less than 2 per cent of the population in the religious conservative Labor voting category. That’s comparable to the support for the HEMP (pro sex, pro marijuana) party in the last Senate election.
Unfortunately, PollBludger doesn’t give proper links, so I can’t check this out. I’ll update if I find a link
