Why do US Presidents Keep Imposing Tariffs?

If I recall Reagan, G.W. Bush, and Obama all introduced tariffs, like Trump has.

If tariffs are bad economic policy why do US Presidents keep introducing them?

Because what makes good economic policy doesn't necessarily make for popular economic policy. Usually because the public doesn't take economists as seriously as other scientists and so prefer to believe what's politically or cognitively convenient rather than what the literature asserts.

Honestly though this would be a better question for a sociologist or a political scientist than an economist.
