US President Donald Trump's war on Iran is becoming an electoral burden for Republicans, with high energy costs pushing some of his longtime supporters to the Democrats, Reuters reports.

In New Hampshire, Reuters interviewed 80-year-old Rick Russman, a five-decade Republican who plans to vote for Democrat Chris Papps: “Gas that costs more than $6 a gallon is a huge expense. ".

Heating oil prices have soared more than 70% in a year, Reuters reported, putting pressure on Republicans in competitive Senate races in Maine, New Hampshire and Alaska.

Trump launched the February 2026 war with some Democratic lawmakers backing the attack and there is a clear sign that military preparations across the Gulf region have been underway for decades and include Republican and Democratic administrations.
