Conservatism has undergone a decades-long transformation from a business-centered, small town set of beliefs into an institutional force of intellectual dishonesty and cruelty against the vulnerable and powerless.
It has devolved from a set of principles invoking smaller government into a ponzi-like scheme of shoveling money from one set of accounts into another through legislative maneuvers like tax cuts. 
Bernier or O'Leary will do nothing more than carry on the devolution of the ideology.
