An Angus-Reid poll taken after McGuinty resigned and prorogued although, as Volkov notes, not long enough afterwards for the news to have really sunk in. Still, Hudak has blown bigger leads before. Hopefully, news like this will convince some of the leadership potentials that its still a job worth pursuing.
PS. Not that moving that gas plant wasn't the worst sort of pandering. The Ontario Libs really laid an egg with that one.
