"Thank you, Nevada. Thank you so much," former Secretary of State Hillary Clinton said in her victory speech after winning Nevada in February.
Winning a state contest during the primary season means you should leave the state with more delegates than your competitors. The operative word there: should.
Hillary Clinton won the Nevada caucuses on Feb. 20 with 53 percent of the vote and was projected to win 20 of the 35 pledged delegates. But that projection is estimated to have gone down by two after county conventions took place.
Basically, not all the delegates are given out during the actual caucus. There are three levels to the system: the precinct caucus, which elects delegates to the county conventions, then county conventions and eventually a state convention, which will finalize the delegate count.
By the time the process is all said and done, the result usually matches the initial vote. Usually.
A delegate switch happened to Clinton in Nevada during her first presidential run. She won the first round but ended up losing the delegate battle to then-Sen. Barack Obama.
And the same thing could happen here. The caucus system relies heavily on voter enthusiasm, and candidates have to make sure that excitement goes all the way until the end of the caucus process.
So as much as it would like to, the Bernie Sanders campaign can't really declare a victory in Nevada. Not until the state convention anyway.
