Postponing Federal Elections and the COVID-19 Pandemic: Legal Considerations [March 20, 2020] [open pdf - 588KB]
From the Document: "On March 13, 2020, Louisiana's Governor invoked emergency powers to announce that the state's presidential primary election, previously scheduled for April 4, would be postponed for more than two months as part of the state's response to the Coronavirus Disease 2019 (COVID-19) pandemic. Other states soon began exploring similar changes, prompting election officials, candidates, and voters to prepare for disruptions that could persist through November's general election. This Sidebar reviews the legal provisions that would constrain any efforts to delay or cancel federal elections during a public health crisis or other national emergency. The first part reviews laws pertaining to presidential elections, and the second part reviews laws relevant to congressional elections."
