so, either as an environmentalist or as an anarchist, if you can vote for a major party that you think can actually win then you help do that. and, the liberals had both a good track record at the local level (if a less good one at the federal level...) and a good platform. so, you do that. perhaps cynically, sure, but you take that gamble - you have nothing to lose and everything to gain.
if the liberals had done anything in their platform, it would have been a worthwhile vote. and, neither the conservatives nor the ndp presented an acceptable environmentalist option....so it's not like there was some better outcome....
but, if you can't do that - which is now the case - then you vote for a protest party, or you don't vote at all.
i repeat that i think i made the right choice in 2015, even if they turned out to be dishonest, in the end - the evidence projected something else.
in 2019, i will be choosing between the smaller parties, if i bother voting at all.
