Canada

The only mention the NDP gets in the story is:

For the past few years, the New Democrats have pushed for a windfall tax on the record profits of grocery giants. Justin Trudeau initially rejected the idea, calling it “simplistic,” then shifted to vaguely threatening to implement it, without following through. Meanwhile, the Conservatives have expressed constant opposition.

It would be interesting to use them as a control, assuming they haven't received the same donations. Are they proposing stronger legislation or policy?
