Any momentum that Democratic presidential candidate Bernie Sanders gains in South Carolina after his win in Nevada could be devastating to Joe Biden.

Former Vice President Joe Biden will finish second in the Nevada Democratic presidential caucuses, NBC News projected Sunday night, and will likely earn seven national convention delegates.

Pete Buttigieg’s campaign has questioned his third-place finish in Nevada’s caucuses and called for the state’s Democratic party to release a more detailed breakdown of votes and address reports of more than 200 problems allocating votes in Saturday’s caucuses.
