A new poll has revealed that 29% of Coalition voters are much less likely to vote for a candidate who supports same-sex marriage.



The Galaxy poll, commissioned by Australian Marriage Forum asked people if there would be more or less likely to vote for a candidate who supported same-sex marriage.



Nearly one third of Coalition voters said they would be less likely to vote for a candidate who supported redefining marriage.  While only 10% of Coalition voters said they would be more likely to vote for a candidate who supported change.



AMF President, Dr David van Gend said same-sex marriage was clearly an issue that could cost the Coalition votes.



“Our study finds strong feeling on this issue among almost a third of Coalition voters,” said Dr van Gend.



“For the Coalition to keep faith with the people who elected it, they must keep faith with their policy.”



Dr van Gend dismissed the idea of the Coalition allowing a free vote on marriage.  “Any change from the present clear party policy on marriage to a position of having no policy at all - just a “free vote” by individuals - would have to be taken to the people at the next election.



“However, given the findings of our survey and the strength of feeling shown for a child's right to have both a mother and father, there is firm political ground for Coalition MPs to stand on with their present child-centred policy on marriage.”



The Galaxy poll was conducted online using a representative sample of Austrlaians and was conducted between 12 and 18 June 2015.
