In the second of a two-part examination of the presidential candidates’ policies, we turn to Joseph R. Biden Jr.’s agenda and how he plans to govern a nation wracked by a public health and economic crisis. The themes of Mr. Biden’s Democratic primary campaign were broad as he eschewed the policy-intensive approach of opponents like Senator Elizabeth Warren. But the onset of the pandemic helped shape and crystallize his policy plans. His approach stands in stark contrast to that of President Trump: Mr. Biden wants to actively mobilize federal resources in addressing the pandemic, an expansion to health care that he hopes will endure beyond the coronavirus. Today, we speak to Alexander Burns, a national political correspondent, about Mr. Biden’s plans for dealing with the current crisis and beyond. Guest: Alexander Burns, a national political reporter at The New York Times.
