Trump stretches ‘America First’ on Iran. His voters are going along with it. - Politico

New reporting shows that many 'America First' supporters are going along for now in competitive states, but party strategists warn that rising U.S. casualties or a prolonged conflict could erode that support and depress turnout among the base. That fragility is increasing pressure on leaders to clarify goals and timelines.
