Kat Lonsdorf’s report on the Army having used most of its long-range precision missiles makes the war’s hidden resource constraints concrete.

The brief

Tamara Keith examines Michigan’s close Democratic Senate primary between Abdul El-Sayed and Haley Stevens, where outsider-versus-establishment tensions could shape the party’s November strategy.

The race also reflects broader Democratic challenges: bitter primaries, House contests, and pro-Israel outside spending complicate the party’s effort to build a coherent electoral strategy.

Kat Lonsdorf reports that the Army has used most of its long-range precision missiles during the Iran war, while Patriot interceptor shortages raise questions about future conflicts and Ukraine.

The episode then turns to Moderna’s mRNA flu vaccine, whose potential speed and adaptability face political opposition and an uncertain FDA decision under Robert F. Kennedy Jr.

Together, the stories test whether institutions can sustain strategic choices under pressure—from campaign coalitions and weapons stockpiles to vaccine regulation.
