tia.yang ( Tia Yang, senior editor): Americans overall are fairly split over tariffs. Broadly speaking, polls this year have shown that increased or new tariffs are slightly unpopular among the public. At least two-thirds of Republicans tend to support them, while a larger share of Democrats consistently oppose them.

In an escalation of his trade war, President Donald Trump moved to put tariffs on nations that levy taxes and fees that hurt U.S. businesses.
