Not really.  Just ignore this repulsive reprobate.  The Last Honest Conservative's every post makes it clear that he is neither last nor honest nor conservative but is instead an obsessed sufferer of Harper Derangement Syndrome and a tiresome and tedious troll and tougher for Trudeau.

Now with Harper withdrawing gracefully from public life, this poor HDS sufferer must find another conservative villain on which to vent his sick spleen.
Trump is the obvious default target choice for him.

Don't feed the trolls is the best way to handle HDS sufferers like this one.
