Democrats gained strong control of both the House and the Senate in the Nov. 3 midterm elections and are expected to target President Donald Trump’s tariff agenda in some form. How effective these efforts to curb the broad-based, price-hiking tariff program can be is an open question.

Democratic wins across geographic regions and demographic groups mean the party will hold up to 56 Senate seats in the 100-member chamber. The new House Democratic majority could reach into the 250s and possibly top 260, out of 435 lawmakers. That’s more than enough to hold successful votes challenging the tariffs the Trump administration has imposed in the president’s second, nonconsecutive term — which, even after an adverse Supreme Court ruling, have continued in other forms. Senate and House Republicans, soon to be in the minority, also may have political cover to vote against Trump’s trade agenda.
