What about the Green Party?
Electoral posters in my riding read "FOR free education, AGAINST shale gas, FOR more taxes for rich people". I've seen other posters in other ridings that also say "FOR free public transit".
I already voted for the green party at least once when I did not know to whom I should give my vote, it was like these guys are cool so let me give them a very humble pat on the shoulders. I voted for Quebec Solidaire in 2012 also because I found Françoise David and Amir Kadir cool, though I really don't want them to win a majority any time soon. Otherwise, they will set the first communist country in North America and we will be enjoying the chants of the Quebec Red Army every morning we wake up.
Free transit for all is not realistic, Mme David mentioned that during the last debate. In 2012, Legault also entertained us with some of those crazy promises. I think that he learned his lesson since then and found out how to back up his promises with numbers which makes him a more credible candidates (that does not mean this his promises are realistic, though).
The green party did not put any posters in my riding, as a matter of fact I have only found out that there are some green party candidates in this mayhem accidentally today. Poor green party candidates, they cannot afford hanging electoral posters in a capitalistic riding like mine where they have zero chances to win.
I am going to start my own party on the next elections. My program will be free hobbying for all and trolls-free review boards (I will have to cut on education and health services though).
