It's obvious that ruling parties have more in common with each other than they do with their own supporters. It was convenient for the Harper regime to restrict access and now it's convenient for the Trudeau regime. It's best not to make excuses for either of them. Governments will look after themselves; even a third party, a more daring outsider, grows more cautious the nearer it gets to real power. We're left to vote for little more than style, with substance remaining more or less the same. It all leads to increased disillusion with democracy itself, and worst of all to the rising appeal of demagogues with simple answers. 
Is the traditional party system -- with its predictable partisanship, with its endless campaigning, with opposing for the sake of opposing -- the best we can do.
