Harper Conservative Party Leader

By the end of 2015, will Stephen Harper announce his resignation as Conservative Party Leader?
Yes: 75%
(Harper does not have to actually resign, just announce that he will resign in the near future.  This question will also be triggered if Harper permanently leaves the leadership through some other means in 2015)

Stephen Harper, the current Conservative Party leader (and Prime Minister) will almost certainly resign if the Conservatives do not form the government after the next election.  Current odds suggest the Conservatives have about a 30% chance of forming the next government (see here - I'm not forecasting this because it isn't unusual enough for this blog).  Harper might also resign if the Conservatives form a very weak minority government (although he might stay on for a while for stability reasons in this case).  There is also always the possibility that Harper will leave office for some other, unforeseen reason.  Overall, it seems that Harper is fairly likely to leave office.
