Bernie Sanders takes a stroll, waving to supporters as Nevada holds key Democratic caucus. Nevada will test his appeal with minority voters, as he looks to puncture rival Hillary Clinton's argument that he is a one-note candidate whose support is limited to mostly white states. After routing Clinton in New Hampshire and finishing a strong second in Iowa, states with nearly all-white populations, Nevada's Democratic caucuses give Sanders his first chance to prove he can win over black and Hispanic voters and compete nationally as the race moves to states with more diverse populations. Public opinion polling has been scarce in Nevada, where Latinos and African-Americans made up nearly one-third of the Democratic electorate in 2008 and are expected to account for more this time. A few recent surveys show a tight race, however. Clinton's campaign has argued she would assert control of the Democratic race once it moved to more diverse states with black and Hispanic populations who have traditionally backed Clinton and have been slow to warm to Sanders. But a Sanders win in Nevada would shatter that perception, fueling new questions about Clinton's strength in a campaign that was once considered a cakewalk for her. It would also raise the stakes for the next contest, in South Carolina on Feb. 27. A Clinton win, however, would halt the momentum Sanders has generated from his 22-point defeat of Clinton in New Hampshire and position her to begin rolling up wins and delegates in South Carolina and on "Super Tuesday" on March 1.
