I don't think he would be changing any of his strictly conservative views any time soon.
This is a serious question, believe it or not (and I preface it by saying I'm not trying to be hostile or anything, I'm just genuinely curious): why do you place so much emphasis on the conservative views (or those that you believe exist) of a potential leader? Like, why does it matter so much in the context of party platform, current policy and current campaign when the party acts as a body or a group rather than as an individual, and the leader is just a spokesperson by and large for the stance of the whole party?
I don't think two of the issues you brought up are at all relevant to the current campaign. Are you just somebody who has put yourself down as a non-LNP voter for life, and therefore you're never going to consider the current offerings and just always look at the overarching 'vibe' you get from the party at any point in time? Or is it just Abbott that turns you off the party? If there were another leader, what would your views be then?
Polonium, yes, I am electing the government this term. I'm not electing them for life. And I know this is probably going to make me sound like a bitch, but I personally don't feel I can sacrifice all the downfalls I see in Labor policy this term by voting Labor even though they are supposedly going to begin supporting gay marriage. As much as I believe in marriage equality, I refuse to be a one issue voter. I've thought about my vote, and I know where it is going this term. It doesn't mean I would never vote Labor in the future and it certainly doesn't mean my stance on marriage equality is the same as the LNP stance at the present time (that it should wait). I do believe action should be taken as soon as possible but I don't want to HAVE to vote Labor to see that action, just based on the other stuff they have put forth.
By the way, the official Liberal position on gay marriage is actually that it's 'not a current priority', which is basically a nice way to weasel out of the situation. It's certainly not what you have posted in reply to Allan and I have a feeling that's why you haven't attempted to show us a quote stating that is the official Liberal position. And importantly, at the present time.
I don't think that being opposed to something 7 years ago 'says enough', especially when a few DAYS ago someone said they don't want to politicise abortion. I think the latter says enough about the validity of using that issue as a basis upon which to cast a vote in this election. Even if Abbott were opposed to Abortion, this is not a dictatorship, and most of the Liberal party wouldn't feel the same way so I'd have difficulty believing that he would ever take any action on his personal concerns should he be leading the country.
