Is statistics a science? Biology is. Some left wingers have a tendency to ignore the bits of those they don't like, just as some right wingers ignore the bits of science they don't like.
You are kind of fucked, as you are going to have to argue in defence of the honesty of politicians to argue against my point and that is never a position you want to put yourself in.
You can't even ask for science denial that all left wing politicians argue in favour of, as not all right wing politicians deny climate change science.
