We saw what happened to O'Toole when he tried to pull that trick.
JT did not win that election by much.
He was lucky that Vaccines and COVID were a potent wedge issue. I doubt that will track for the next election.
I wouldn't put it past JT to give PP the Stockwell Day treatment and try to call a snap election. The NDP may not be down, they're in defacto government right now.
