The Los Angeles Times‘ Cathleen Decker reports Donald Trump and Bernie Sanders have tough challenges ahead as the presidential race widens. Trump and Sanders, who are considered the anti-establishment candidates in their respective parties, face a changing electorate and will have to translate their regional populist message into a national platform. “After a riotous eight days that ended with the first successful Democratic insurgent win here since 1984 and the first Republican win ever by a TV host and real estate entrepreneur, the races now diverge,” writes Decker. “Tuesday marked the end of regional contests and the beginning of a national campaign, with all the financial and logistical demands that entails.”
