LAS VEGAS (AP) — Bernie Sanders scored a commanding victory in Nevada’s presidential caucuses, cementing his status as the Democrats’ national front-runner but escalating tensions over whether he’s too liberal to defeat President Donald Trump. As Sanders celebrated Saturday night, Joe Biden was in second place with votes still being counted. Pete Buttigieg and Elizabeth Warren trailed further behind. They were all seeking any possible momentum heading into next-up South Carolina and then Super Tuesday on March 3. Nevada’s caucuses were the first chance for White House hopefuls to demonstrate appeal to a diverse group of voters in a state far more representative of the country as a whole than Iowa and New Hampshire. Sanders, a 78-year Vermont senator and self-described democratic socialist, won by rallying his fiercely loyal base and tapping into support from Nevada’s large Latino community.
