Political Parties: What's your source?

I found myself in conversation with a United Australia Party representative at the local polling booth at last Saturday's federal election. He said, "We all want freedom, right!"
"Mm, that's a value that comes from somewhere," I replied.
He nodded, "it's all about goodness and kindness, right."
"And those values come from somewhere too."
"Yeah, err..." he stalled.
I bailed him out: "Y'see, I like a lot of your values, but I'm voting Australian Christians because they are very open about where their values come from - it's the Bible, it's God, the foundations of the Judaeo-Christian worldview. So I know whatever questions they face, they will try to figure an answer from that reference point. What about the other parties - what are their reference points? Clive Palmer? Marx's Communist Manifesto? Prevailing popular opinion?"
So that's my basic question for every party and representative: "What's your reference point?"
