Like Trump vs Clinton, the only way the PC party could get back into power with O'Leary would be if the Liberal candidate was even less acceptable, making him the lesser evil.  O'Leary is unelectable in French Canada and in the intellectually advanced parts of the country that demand immersion classes for their children and, of course, bilingual political leaders.  Moreover, O'Leary is also unelectable in those ridings that, even more than the US, have liberal democratic values.that are disgusted by his posting a video of his firing a simulated machine-gun at his rifle club as murdered Muslims are burried in Quebec. With Trudeau still running at over 55% in the polls and maintaining his credibility domestically and internationally, the Conservative party would be well advised to choose a leader from amongst those that are electable..
