* trudeau is dangerous for canada, but scheer will have a hard time fighting against trudeau's populist polices.  
* trudeau practices identity politics, elevating certain groups, including the islamic community, while alienating others. 
* trudeau also believes in equality of outcome, and arbitrarily taxes success and redirects cash to his voting groups. this  populist approach will diminish innovation, and encourage those with desired skill-sets to leave canada (why stay when the top marginal tax rate exceeds 50%, plus you are not provided with other benefits.. like child care subsidies, etc). 
*history has taught us that these policies are dangerous.. but any politician that attempts to take the punch bowl away will be punished..
