Poll shows Americans split on Iran policy: diplomacy vs. regime change across party lines

A Reagan Institute Summer Survey of 1,555 nationwide adults (±2.5 points) finds Americans nearly even on Iran policy: 39% back a negotiated settlement that leaves Iran’s current government in place with verifiable limits, 36% support replacing the regime, 16% favor a weakened Iran, and 8% don’t know. Democrats largely back diplomacy (52%), Republicans prefer regime change (about 50%), with MAGA Republicans at 51% for regime change. The poll accompanies the Trump administration’s 60-day memorandum of understanding with Iran aimed at reducing tensions and pursuing a broader nuclear deal.
