And now, to the very difficult business of moving forward.It's looking like state lawmakers might do the right thing and grant one of Senator Ted Kennedy's final wishes, installing somebody to act in his stead until voters choose a permanent replacement. That somebody should be Mike Dukakis. Do I hear a groan or two out there? It's possible some of you might not share my soft spot for the former governor. He's too liberal for some, too much of a scold for others. He's obsessed with trains and trash. Also, the tank and the helmet.
