If the CPC is going to succeed in the next election, it has to do something to attract and create Red Tories again. If the Tories are willing to wait through another Trudeau win, then they can pick a Reform candidate and wait for voter fatigue. Harper was able to succeed because support was split fairly evenly between the NDP and Liberals, but right now the NDP is not a contender. That points towards Chong, who seems the most viable candidate on the Red Tory side.
