The Washington Post is trying to better answer that question by conducting quick polls, in which we text about 1,000 Americans after a breaking news event and publish their answers within 24 to 36 hours.
TLDR: People approve/disapprove around 50/50 with slightly more people disapprove. The tariffs on Mexico and Canada is more unpopular than the strategy of tariffs more generally. The most divergence is about concern for the consequences: 75% are concerned. In other words: It's not at all a rare combination to approve of the strategy despite being concerned about the consequences. I find this quite striking.
