I thought it might be worth resurrecting this thread as I think things are a bit in flux right now. For the first time in over 6 months, Harper's Tories can say that they led in a poll: an Abacus survey released the 23rd had them up 34% to 33%. In addition, Angus Reid has the parties tied at 34, a gain of 4 since their last federal poll. Is this a trend shifting back in Harper's direction, or just a temporary blip? We will have to see in 2015.
For the polling year in review, this article isn't bad:
