A Roper poll in September 1939 asked how the U.S. should frame policy towards the warring nations. Among respondents, 37.5 percent favoured eschewing partisanship, but continuing to sell goods to all parties on a cash-and-carry basis; some 23.6 percent opposed any commercial traffic with any combatant; just 16.1 percent favoured a modification of neutrality to offer aid to Britain and France if they were threatened with defeat. Interventionism enjoyed most support in the southern and western states.
