Louisiana's presidential primary was again delayed until July 11 — the second time the state rescheduled the contest. Voters in the state can request an absentee ballot if they're at a higher risk for COVID-19, have tested positive or been advised by a doctor to self-quarantine.

The big picture: Since Sen. Bernie Sanders dropped out of the 2020 race, former Vice President Joe Biden has been established as the presumptive Democratic nominee, and President Trump has already gathered enough delegates to clinch the Republican nomination. Most of the remaining 18 presidential primaries have been postponed from their original dates and more than 20 states have stay-at-home orders in place.
