That the Conservatives may need another Harper to avoid the mess they are in has most to do with the unholy, for lack of a better word, alliance of the Reform and Progressive Conservative parties.

Unfortunately, there is little or no room for real P Cs in the current Conservative Party.   They will not be heard or listened to by the other side.  Harper could control the most viscous tendencies by sheer will and absolute control, but even he was worn down and his grip slipping in the end - most obvious in  Leitch and Alexander destroying  years of work trying to lure minorities into the Party.

Not a Conservative supporter, I must say I miss the exchange of ideas that used to exist.  At least, the old PCs like Dalton Camp, whom I admire, had the best interests of Canada in the forefront.  the best thing that could happen is to split the Party and relegate the "Reform" element to outlier status.  Then true Conservative values, after a rebuilding could be discussed in a sane environment.
