A rapid succession of Senate Republicans publicly challenged President Donald Trump on issues from the Iran war to his summit with Chinese President Xi Jinping. The backlash, simmering throughout Trump's second term over affordability concerns, burst into public view as lawmakers face a difficult midterm election environment. Retail gasoline and diesel prices have risen, and financing costs for government debt have increased since the Iran war began.

Public GOP Defiance

The GOP backlash burst into public view as a rapid succession of Republicans challenged Trump on everything from the Iran war to the president's "lavish" summit this week with Chinese President Xi Jinping. Florida Republican Maria Elvira Salazar cut a video telling Trump that his immigration crackdowns have gone "too far," as she battles to retain her House seat in a Miami-area district heavily impacted by the administration's deportation policies. Republicans have long been loathe to openly criticize the president, who has wielded an uncommonly strong hold over his party and retains long memories about who has crossed him.

Electoral Pressure

Back in May, eight Indiana state lawmakers who defied Trump on a redistricting plan faced their primary voters, and only two won. The president that month similarly ended Texas Senator John Cornyn's political career by backing Ken Paxton's primary challenge instead. Those same Republican lawmakers who held tight with Trump through the primaries are now facing a general election environment and a very different electorate. They now have to contend not just with GOP voters, but Democrats who've always opposed the president, as well as disaffected independents who've drifted from Trump over economic concerns.

Economic Strain

Retail gasoline prices are up, and so is diesel. The cost of financing government debt has risen since the Iran war began, driving up the cost of mortgages, credit cards and consumer debt. A confident White House that has unapologetically pursued all of its priorities at once, from tariffs to getting Trump's name on the Kennedy Center, is increasingly seen as unfocused on the costs Americans pay to go about their daily lives.
