Makes no difference, the drop in soybean prices started before Trump did anything.
It does even make sense to point at Trump. One, its Chinese tariffs. Two, Trump imposed tariffs on other countries for the very same reason you support them for your country Canada.

What we have here are facts vs fiction.
