Data journalist Nate Silver tweeted Friday there is a “high probability” of a brokered Democratic National Convention in 2020 because of the potentially large field of candidates and the planned reduction of superdelegates in the nominating process.

The term “brokered convention” refers to the Democrats potentially not selecting a candidate in the first round of delegate voting due to one not winning the requisite number of delegates to clinch the nomination.

The Democratic Party “unity commission” that has been working on a list of recommended party reforms over the past year is reportedly planning to “recommend dramatic cuts to the individual voting power of superdelegates and new rules around caucuses and primaries to improve access for voters and recordkeeping,” according to ABC News.

The commission is meeting Friday and Saturday to finalize the list.
