Well there are numerous examples of right wing parties or the NDP completely devastating or wiping out their parties in the face of corruption.
Consider the PC government federally after Brian Mulroney left and Kim Campbell disappointed by saying everything was fine and there's no need to change. They went from being in power to being able to hold caucus meetings at a medium-sized booth at Denny's. And then the party was eventually wiped out completely and replaced.
Consider the NDP in British Columbia when they had their scandal of the tail end of the 20th century and we're reduced to two seats as I recall. Likewise the conservative party which was known as the social credit for absolutely bizarre reasons was wiped out after the Vanderzalm Scandals.
There is a willingness for Canadian voters on the right and the farther left to absolutely devastate if not completely destroy their political party if it is perceived that they have done something unethical. The conservatives most of all but the NDP as well
But there is no willingness on the part of the liberal sister they may knock their party out of power but they will never punish them even for severe corruption the way the conservatives and even the NDP will
