@Setanta,
Being an AMerican I did not realize that she was kidding. I always take political threads at their face value and try , at least initially, to do some research and surround myself with facts , in this case the facts being that can a non human or specifically, in this case, a vegetable of the cole persuasion seek high office and run an effective campaign to be elected PM ?.
I do not think that this sort of nomination is without precedent in Canada. There have been previous attempts at people placing into nomination several varieties of livestock and wildlife. However, I do think that, in the recent past, someone had entered a pumpkin into a race for high office in One of the Prairie Provinces. Prior to the election a sad event occured,The pumpkin succumbed . It had ,vegetally speaking, "peaked" too early in the campaign and suffered from a terrible case of oxidation and loss of tone. This left voters with the question of whether the said pumpkin could complete (his or her) term without serious facial suregery.
Course there was the moose in New Brunswick who was forwarded in a Provincial campaign as a write-in candidate. The moose just disappeared around September of that year. There was sufficient evidence to support charges surrounding the moose' disappearance . Coupled with a suspicious "barbecue" that was held in Blissfield N B about 3 weeks before the election, the moose name was quietly withdrawn from nomination the Monday after the barbecue.
