Analysis: Why the Trump effect is different in 2026 than 2018

An analysis suggests that Donald Trump's political influence, often termed the "Trump effect," is manifesting differently in the 2026 elections compared to 2018. In 2018, the midterm elections largely saw a significant backlash against the incumbent president, leading to substantial gains for the opposing party, mirroring historical trends where voters express discontent with the party in power during midterms.

As of July 2026, with President Trump currently in a second, non-consecutive term, his approval ratings remain low, particularly concerning the economy, which is a top issue for many voters. However, Democrats are not attracting the same proportion of voters disapproving of Trump's performance as they did during his first term. This indicates a shift in voter behavior where direct opposition to the president may not automatically translate into support for the opposing party.

Furthermore, a critical difference in 2026 is the administration's intensified campaign to undermine election safeguards and spread disinformation, leading to concerns about the integrity of upcoming elections. These efforts, including pushing for restrictive voting legislation, present a new dimension to the "Trump effect" beyond traditional voter sentiment.
