If accurate - this poll shows the Conservatives issues in a nutshell:
Selecting Poilievre as a leader - they win Alberta/Saskatechwan and Manitoba by wild margins, but lose Ontario, Quebec and the Maritimes.
Selecting Charest as a leader - they drop a bunch of points in the Alberta/prairie provinces (to PPC/Other) but still win comfortable but also win Ontario and the Maritimes and pass the Liberals in Quebec
