DES MOINES, Iowa (AP) – Across an arc of vital swing states, the coronavirus has put politics on an uneasy pause. Political fights are raging among state leaders from Iowa to Pennsylvania over the handling of the pandemic’s impact. Protecting public health versus restarting the economy, along with arguments about the limits of executive authority, have taken the place of the national political debate that’s typical of presidential campaigns at this point. Meanwhile, presumptive Democratic nominee Joe Biden has built little campaign structure across the region. President Donald Trump is relying on state GOP headquarters for his operations, though they too have been largely empty.
