The presidential nominees support tariffs like crazy for multiple reasons. In Stossel's video, three main reasons stick out as to why they support tariffs. The support of tariffs comes from the drive to protect from foreign stuff, and shows that they are a true patriot and protector of American goods. This causes the American people to support them, and cast their votes to them. They support businesses to show their protection of their short term profits and gain their votes and support. Finally, they support the hurting minorities who lost their jobs due to the random loss of jobs that the tariffs "protect against." The Support of the loud minority is common to get more votes and show their support for all.
This is true. Even though both parties oppose each other in many ways, they both wanted tariffs even though it is worse for the economy.
I agree, tariffs are so supported in the US because they protect American goods, even though they are not what is best economically.
