I have met some who say they are suffering from buyer's remorse regarding Little Potato.  This  explains why CPC support is up about 5% from the 2015 election, and rising.

As Trudeau's unfitness for leadership of a G 7 country becomes ever more obvious, as even more promises are broken or twisted beyond recognition, as the next election gets closer and voters begin to give some thought to their choice for 2019, and most of all as the CPC presents a new leader (I'm betting Raitt, O'Toole, Chong, Bernier or Scheer) and rolls out a new platform, more voters will opt for the CPC.

To guarantee  a Conservative victory in 2019 the NDP must move from life support (currently 12%  even less that Wynne-Bag in Ontario) to around 20% at the LPC's expense.  Given the right new leader and an increasing realization by millennials who deserted the NDP for Justin as to  how much they have been had, this will happen.

Ironically, only Trump goosing the US economy (DJ record today) might save Trudeau.
