It wouldn't be right to call the calamitous end of the General Assembly session a failure. The word "failure" implies that those involved were trying to do the right thing and were for some reason unsuccessful. What happened Monday night, as the politics of an ill-considered gambling expansion bill tangled up a sensible compromise on taxes and the budget, was something quite different, a mixture of sabotage, negligence and too-cute-by-half gamesmanship. It reflects poorly on Maryland's leaders and belies the seriousness of the one real matter at hand: Who should be asked to pay more to maintain crucial state services, and how much? Gov.Martin O'Malley, Senate President Thomas V. Mike Miller and House SpeakerMichael E. Buschneed to bring the legislature back for a special session to resolve that issue, and they need to get it right this time.
