Trump still shapes the Republican Party's post-Trump future

American voters have signaled Republicans must decide their party's future after Donald Trump, though the weakened president remains a dominant force. His succession question is now urgent since he cannot run again and has become electorally toxic. Trump's 2024 winning coalition fractured spectacularly, with young men shifting 38 points to Democrats and Latino voters 28 points. Republicans face a dilemma: distancing from Trump risks primary losses, while close association harms general election prospects. Most Washington Republicans publicly stay quiet while privately blaming him. Vice President JD Vance, the leading successor candidate, publicly blamed the Iran war for the loss, a rare break with Trump. Trump responded mildly, reportedly approving Vance's statement beforehand. Trump remains focused on his legacy, and his unpredictable behavior means his current tolerance offers no guarantee for the future.
