You only have to weigh up the number of times you hear her name in the media and then whether the news story is positive or negative.
A politicians performance will be judged on what they do for the good of the section of society their ministry represents. She is a disaster because a) she has no backbone to stand up to the vested business interests or worse still b) she takes very good care of vested interests and things suffer as a result.
She is a poster child for the sorry state or our politicians. We need to take a leaf from France's book and they need to take a leaf from the UK's book. We should cause more of a racket when we are pushed around and they should have the honor to resign their positions when they are either in error or make significant mistakes. We need to show them that they are answerable to us, not the other way around.
As for Mr. O'Leary, we all know he is a ruthless businessman, but it is that sort of drive and ingenuity that makes change and keeps the world changing (for better or worse, but at least its a change of direction). Yes he may have an ulterior motive, but in the end it is about Mary's ego and that of the government thinking that no-one can push them around, again that they are answerable to no-one
