I changed my vote from Green to CPC based on:
May's poor performance so far
Sheer may not be flashy but he is intelligent and steady
My local CPC MP is an good MP and far better than the other candidates
Sheer has good experienced people like Lisa Raitt.
Trudeau has shown little respect for women and he is just not a good fit for the task. (Kudos, though, for the NAFTA success.
I'm waffling between Green and CPC, too.
I'm not 100% sold on either of their platforms and have some differences with both of them on certain issues.
As they say - it's a bit like choosing which STD is right for you.
