In 2025, President Trump’s tariff agenda led to an average tax increase of $1,100 per household – the steepest U.S. tax increase since the 1990s. American businesses are trapped in this chaotic policy and must choose between shrinking profit margins or passing the costs onto already hard-pressed consumers.
Despite the clear and growing economic impact of Trump’s tariffs, the political response has been fractured and lackluster. We have seen occasional flashes of bipartisan courage, with leaders like Senators Rand Paul and Mitch McConnell breaking ranks to challenge this overreach, but too many in the GOP lack the courage to cross this administration. At the same time, many Democrats are still struggling to offer a strong message against tariffs that comes across as genuine when so many have protectionist pasts.
Right now, the stakes couldn’t be higher. The Supreme Court will soon decide if the President can use the International Economic Emergency Powers Act (IEEPA) to impose tariffs, and the White House just announced a 10% tariff on eight European nations as a pressure tactic to force the sale of Greenland to the United States. Regardless of the court’s decision, the U.S. Senate must not abdicate its responsibility as the Executive Branch violates the separation of powers, and it must work to restore it’s rightful congressional authority over trade.
Our Senate Tariff Response Index evaluates every member of the U.S. Senate across a few core pillars: their prior record on trade issues, their voting record on trade issues under the current administration, and their overall messaging, leadership, and stances against Trump’s tariff agenda.
