FILE - In this July 26, 2016, file photo, delegates cheer as Democratic Presidential candidate Hillary Clinton appears on the screen during the second day session of the Democratic National Convention in Philadelphia. Democratic presidential candidate former Vice Presiden JoBiden’s presidential nominating convention will highlight the U.S. political spectrum from the left flank of New York Rep. Alexandria Ocasio-Cortez to the Republican old guard of former Ohio Gov. John Kasich. But that doesn’t mean there’s room for every prominent Democrat who would get a share of the spotlight at a routine convention taking place without the backdrop of a pandemic.
