Three Senate debates showed Republicans on the back foot over tariffs, gas prices, and the Iran war — bad news for Trump-aligned candidates heading into the midterms.

• Tariffs came up again and again, and Michigan's Mike Rogers has no clear position on them — he has praised them and criticized them, depending on the day.
• With gas near $4 a gallon, voters have far less patience for tariffs and corruption than they did in Trump's first term.
• The Iran war is so unpopular that even past supporters like Rogers are backing away from it.
• In Georgia, Jon Ossoff tied Mike Collins to white-supremacist staff and family ties and to a budget bill that cut Medicaid while handing tax breaks to data center developers — Republicans have largely given up on the state.
• Ossoff dodged a direct question on whether Israel is committing genocide in Gaza, punting it to the International Criminal Court — a safe answer that pleased neither side.

Outlook: Expect tariffs, gas prices, the Iran war, and data centers to stay the core attack lines through November, with Ossoff looking comfortable and Michigan still close.
