Justin Trudeau is to ask the Governor General to ring the bell tomorrow for a 40-day federal election campaign.

It pits a gaffe-prone Liberal government against a Conservative Opposition that has yet to capitalize on the struggles of its main rival.

The campaign leading up to election day October 21st is also promising an interesting undercard — a fight between Jagmeet Singh’s foundering N-D-P and the resurgent Green party of Elizabeth May.

All the parties have been sparring for weeks, preparing for what many predict will be a brutal battle for the 170 seats needed for a majority.
