Vice President JD Vance on Wednesday said the US war with Iran was to blame for the Republican Party’s crushing defeat in the midterm elections, arguing that the conflict was the main reason voters across the country swung hard towards the Democrats. “The reason we lost is the war. The President himself said so last night,” Mr Vance wrote on X, referring to an interview in which Donald Trump told Fox News that the Iran war was “a part” of why the Republicans had lost.
