Trump's political influence grows as he shapes GOP primary and widens Canada trade war

Donald Trump continues to wield substantial influence within the Republican Party, significantly shaping primary elections. In 2026, his endorsed candidates have achieved a high rate of success in GOP primaries, including notable victories where challengers backed by Trump unseated incumbent Republicans. This trend highlights his enduring impact on the party's direction, particularly in closed primary systems where his base demonstrates strong electoral turnout.

Concurrently, the trade dispute between the United States and Canada has intensified. President Trump initiated new tariffs on various Canadian goods, such as automobiles, alcohol, and dairy products, citing unfair trade practices. Canada has responded with reciprocal tariffs on U.S. imports and implemented "Buy Canadian" policies, further escalating the conflict following failed trade negotiations. Recent measures by the Trump administration in September 2026 included executive orders to ban specific Canadian products and impose additional tariffs.

Beyond his current political and trade actions, Trump also faces ongoing legal scrutiny concerning past policies. The Supreme Court recently struck down his January 2025 Executive Order 14160, which attempted to redefine birthright citizenship. Additionally, the Court overturned a long-standing precedent regarding a president's authority to remove members of independent agencies, stemming from a challenge involving a former Federal Trade Commission Commissioner. Other lawsuits continue to challenge his administration's actions related to healthcare regulations and immigration policies.
