The word "ideology" is thrown around a lot in this place, and it's usually one side accusing the other of doing something without any other justification than they believe in it. But, the thing is, all of us have ideologies, because all of us have values and philosophies. Those values and philosophies are actually the things that we run election campaigns on. They're the underlying principles of our policies that we take out on the hustings and we ask the people of this country to vote for. Almost all of us can find evidence for the things that we believe in, but, of course, not all of that evidence is made equal.
