This poll is both encouraging and worrisome for Greens: encouraging because, though slight, overall support for the GPC has risen, but worrisome in that 72% of those apparent supporters claim they might change their mind. That's an extremely high number, one that suggests a lack of commitment. Were these potential voters to do so, the migration would no doubt be to the Liberals, who are gathering momentum, not the Harperites or the Dippers. Thus the absence of Elizabeth May in the federal debates becomes even more crucial. Tomorrow's court appearance means everything.
