The more one thinks about this, the more difficult a voting decision becomes.  For a variety of reasons too numerous to list here, I think that none of the parties merits a majority government win.

John Horgan and NDP are just too slippery to be trusted.  They have already done a significant backroom union deal before even being elected.  They have agreed to amend the Labour Code to abolish the secret ballot for union certifications, and conveniently failed to mention that in their election platform.  Perhaps not so coincidentally, the Steelworkers have donated $600K+ to the NDP.

The Greens simply aren't ready for the big stage.  Perhaps in a minor role holding the balance of power in a minority situation but even that is a risky stretch.

Would being knocked down to minority government status sufficiently chasten Christy Clark and the LIberals to cause them to clean up their ways?  Doubtful.  More likely to engage in gaming the system looking for a snap election opportunity.
