Okay let the cheering and guessing begin - Wally does down by 32 votes in Delta South - so who might be the next AG - presume that they will want a lawyer - I believe that there are only three among the Liberal caucus - Bill Bennett, Mike DeJong and Barry Penner.
Bennett is too much of loose cannon - DeJong may want to continue his work on First Nations treaties and does Penner want to give up the Environment portfolio which he seems to enjoy to take on the thankless job of AG.
So here is another scenario while unlikely can't be ruled out - given that you don't have to be elected to be in the cabinet - with Ed John being the last such case - he is re-appointed AG and the Liberals look for a safe seat to parachute him into in a by-election - would they suddenly find that the oldest member of their newly elected group suddenly becomes very ill and needs to step aside thereby allowing Wally to win a by-election in a safe seat.
To my knowledge - the oldest member of the Liberal Caucus is Ralph Sultan who is only 75 or so.
