MORE in pledged delegates, according to its analysis of final counts from Nevada. 

The campaign said it believes the final precinct results that trickled in from Clark County show Clinton will win one additional delegate from the 4th District, giving her 20 delegates to Sanders's 15. 

That total would put Clinton at 52 pledged delegates overall, compared to 51 for Sanders. 

"We expect to build on this pledged delegate lead — which does not include support from the elected officials and party leaders known as superdelegates — later this week in South Carolina, on Super Tuesday and throughout March," campaign spokesman Brian Fallon said in a statement released by the campaign. 

When those superdelegates are added, Clinton's lead balloons. She has locked up about 451 party leaders, according to RealClearPolitics, while Sanders has support from about 20. 

Superdelegates make up 30 percent of the total delegates to the national convention needed to secure the Democratic nomination. While the party leaders are not bound and can change their minds at will, the huge lead gives Clinton a significant safety net.
