Of course Ambrose and the CPC brass will try to put the best face on this but I think the truth is that she has seen enough from her close in vantage point to have reached the conclusion that unless Trudeau and the Liberals make a massive blunder (which is still possible) 2019 is not going to go well for the CPC.

Better to get far away from the flying pucky and consider an untainted comeback in 2023.  Otherwise, what necessity is there for her to resign as an MP?  On offer from Murray Edwards that she couldn't refuse?
