How could either Mulroney or Campbell win the 1993 election with a POD of 1990? After dissolution, the Tories and Grits were tied 35-35 on Sept. 20, 36-31 Liberal (still workable) and then vaporized for thirteen years...
You can have Jean Charest, who could pull off a minority government. I'm unsure about a majority though. You need to avoid the CF-18 controversy to keep the West and pass Meech or Charlottetown to save Quebec for Mulroney.
