A clip of Tucker Carlson trashing Republican Senate candidate Mike Rogers has set off a Republican civil war, and it is bad news for the party's hopes of holding Michigan.

• Carlson said he would not vote for Mike Rogers "at gunpoint," which many read as an implicit nod to Rogers' Democratic opponent, Abdul El-Sayed.
• Rogers is a longtime hawk and mass-surveillance backer who already lost a Michigan Senate race in the year Trump won the state.
• Republican figures are now demanding JD Vance publicly attack Carlson, exposing a deep split between the party's pro-Israel wing and its younger anti-war base.
• El-Sayed is running a leftist platform wrapped in patriotic, America-first framing: stop sending tax money abroad, spend it on health care at home.
• Democratic Party leaders quietly want him to lose, because a win in a swing state would destroy their "only moderates are electable" argument.

Outlook: El-Sayed is favored to win in November, and the size of his margin will shape the fight over the Democratic Party's direction into 2028.
