If you are an American concerned about the impact tariffs will have, you should contact your three Members of Congress.
Every Member of Congress keeps records of how many calls they get on a given issue. One unique call is believed to represent the feelings of 1,000 voters and everyone wants to get re-elected. Your phone call is a point on the board encouraging them to act. It doesn't guarantee action of course, but it shows that you as a local voter care. All Members of Congress want to get re-elected.
[5Calls](https://5calls.org/) will give you all the numbers you need and a script you can use. [This is the tarriff script](https://5calls.org/issue/trump-tariffs-canada-mexico/). You might also want to look at [the CFPB script](https://5calls.org/issue/overdraft-fee-cap-hj59-sj18/). It can be helpful to cut and paste the script into a doc, read it aloud, and make adjustments until it feels natural and represents your views.
If you decide to call, it is important that you be polite. The entry level staffer answering the phone does not deserve to be yelled at. Completely losing your mind on the phone also makes you easy to dismiss.
