If it's credibility you want, don't screw up the details
It was a week in which Fine Gael would like to go out and come in again - so they could start their campaign all over again. "I'm not going to get into economic jargon here because the vast majority of people don't understand."
With those words Enda Kenny got the dubious distinction of the "first gaffe of the campaign". First off, he made it apparent that he had not boned up on just how much money his Government would have to spare over the coming five years. Then he made things much worse by managing to insult people's intelligence. Enda dropped the ball - and then he just dropped it again.
Perhaps it is best summed up by noting that the Taoiseach's gaffe allowed Sinn Féin to briefly steal the role of the economically sensible ones.
