The Bernie Sanders campaign is using their record-setting fundraising to aggressively extend the battlefield for the Democratic nomination into Nevada.Sanders needs to win an early state whose voters are outside of his white progressive. A win with Nevada’s large bloc of Hispanic voters would immediately ease doubts about his national electability. The campaign will come down to how he performs in the first four states. Sanders needs to win at least two of the first four contests, andto demonstrate that he can win with the women, African-American, and Hispanic backbone of the Obama coalition. If Hillary Clinton wins three of the first four states, she will have huge momentum heading into Super Tuesday. If Sanders splits with Clinton, it will change the perception of the Democratic primary.
