This isn't really a Left vs. Right issue. There are conservatives (Jeff Sessions, etc) who support tariffs just as there are labor Democrats who are pro-tariff, although they support them for different reasons. You can say the same thing about foreign policy: interventionism vs. "isolationism" is not a Left/Right issue since there are people from the Left and Right sides of the aisle both for and against various foreign wars and interventions.
What about the other issues?
Tariffs are taxes. If you support higher tariffs you support higher taxes.
Higher tariffs don’t solve anything.
Lower taxes and tariffs solve just about everything.
