The number of extra unpledged delegates (superdelegates), who after the first ballot at a contested convention[لغات أخرى] participate in any subsequently needed nominating ballots (together with the 3,979 pledged delegates), was expected to be 771 as of December 2019, but the exact number of superdelegates is still subject to change due to possible deaths, resignations, accessions, or potential election as a pledged delegate.[1]
