Dr Davis used a radio interview on Thursday to remind voters why he walked away from the LNP and from parliament. He said he felt he had no option but to force a kind of mini-referendum on the changes to electoral donation laws, and the Crime and Corruption Commission. “I could have (stated the concerns in parliament) but I was encountering an enormous amount of hostility in speaking out on those issues,” Dr Davis said. “They were not … trivial matters. They were issues that get to the heart of our democracy, that caused a lot of grief in Queensland in previous years.” He said he didn’t want to be part of any “perception that we were not always putting the public interest first”. “So, I felt it necessary to go back to the electorate and ask them to have a say on what was really important,” Dr Davis said. “Who do they trust and why do they trust them, both the individual and the party they represent.” Dr Davis would not say which way he’d be voting on Saturday. He said he hasn’t spoken to the premier Mr Newman, who holds the neighbouring electorate of Ashgrove, since he quit the parliament. “I don’t think that would be helpful. I was fired (as assistant health minister) for my stand on these matters and I think that probably gives some indication of how far apart we were on these particular issues.” He had a final parting shot for the premier, when asked if his leadership style was a problem. “I think there’s a whole style of politics that could be a lot better,” Dr Davis said. “I never got the perception that we had great statesmen present in this state of Queensland, and I think we’re the poorer for that.”
