WASHINGTON — Support among Republican voters for the preliminary peace deal with Iran has declined significantly as more details about the agreement have become public, according to a recent survey by J.L. Partners.

Initial polling found that 62% of registered Republican voters supported the deal, with only 20% opposed. However, after being presented with specifics of the memorandum of understanding (MOU) signed by President Donald Trump last week, support dropped to 32%, while 44% labeled the deal a “bad deal” and 15% responded neutrally.

The poll highlighted that Republican respondents were particularly concerned about certain provisions in the MOU. These included the waiver of sanctions permitting the sale of Iranian crude oil and the U.S. commitment not to impose new sanctions during a 60-day negotiation period. More than half of GOP voters surveyed (57%) said they would be less likely to support the agreement upon learning that it loosens sanctions without requiring Iran to halt funding for terrorist proxy groups or to dismantle its nuclear and ballistic missile programs.

President Trump defended the approach during the recent G7 summit, questioning the fairness of restricting Iran’s missile capabilities while allowing similar armaments for Saudi Arabia. “Am I going to let Saudi Arabia have missiles, but [Iran] can’t have them?” he said. “It doesn’t work that way.”

The findings illustrate a shift in Republican voter sentiment as the administration’s Iran policy has unfolded, reflecting skepticism about whether the agreement adequately addresses core U.S. security concerns. The evolving stance among GOP voters may influence ongoing debates in Washington over the next steps in diplomacy with Tehran.
