Actually, Dom Agostino won only a little over 52% in 2003--1 1/2 points *lower* than in 1999, despite the McGuinty landslide.  The NDP's Bob Sutton, meanwhile, grew his share by over 10 points.  So the signs of the future were there.

 (Among other victorious Liberals with a lower share in 2003 than 1999 was Caroline DiCocco in Sarnia--who went on to be one of the few defeated Liberal incumbents in 2007.)
