IT is a tragedy, and a very illustrative one, that as the Government elected with the strongest mandate for change in the history of this State prepares for the resumption of the Dáil today that polls suggest that something around half of the Coalition seats are in jeopardy. Had that once-in-a- lifetime mandate been grasped as energetically, and as forcefully, as it should have been then the prospect of such a purge could be dismissed with confidence.
