A senior Government source told The Bugler that Fielding had built his career on small minded political opportunism, and he was unlikely to change that now.
"Take a look at his views on gay rights, abortion, the role of women. Open minded isn't something I think of when I hear Steve Fielding," the Government source said.
An Opposition source agreed with the assessment of Senator Fielding.
"He's so conservative, so close minded and pig headed. On top of that now he's denying climate change in man made. Why isn't he in the Liberal Party?"
A spokesman for Senator Fielding said the Victorian Senator had an open mind on many issues other than climate change, such as what restaurants to eat at and praying kneeling or sitting.
