It's the trouble with people making equivalences between "a particular person calling themselves an economist" and "economics". There are hundreds of thousands of people with economics degrees, it is trivially easy to find one who says what you want to hear. But then, that economist's words are often taken to reflective of economics as an entire field of study - regardless of the reasoning behind it, or how many other economists actually agree. So most economists may have totally sensible reasons for supporting Policy A, but when one dissenting economist supports Policy Not-A, the "consensus view" gets ignored. I don't know why this is. Maybe because people feel competent to judge economic reasoning in a way that they don't with other fields (and which might lead them to seek more opinions.)
