Hey there! I really like your stuff and I'm kinda confused on the difference between the NDP and the Liberal party?
Liberals are centrists, and a bit to the left.
The NDP is more left.
Its the NDP that campaigns on a $15/minimum wage, not Liberals. Many NDP parties have campaigned on eliminating/reducing student debt/tuition, and expanding medicare (to cover things like drugs/dental/etc). Liberals have not (the Liberal Party I’ve seen come close to that is in Ontario to reduce tuition for low income students but its still not free tuition as $3000 needs to be paid as a minimum). If Bernie Sanders was Canadian he’d be in the NDP, not a Liberal.
Liberals tend to be socially Liberal (i.e. they care about LGBTQ and Women’s rights), but also have quite Conservative policies when it comes to things like foreign policy and economics (such as approving as many oil pipelines as they can or pushing for big free trade deals like the trans pacific partnership). The Liberals middle class tax cut for example; the highest benefit goes to the top 10% of the population. Low income Canadians get nothing.
