Clinton opens big delegate lead over Sanders after winning Louisiana
Democratic front-runner Hillary Clinton won in Louisiana on Saturday, while her rival Bernie Sanders, a US senator from Vermont, won in Kansas and Nebraska, in results that did not substantially change Clinton's big delegate lead.
Clinton has opened up a big delegate lead and Sanders might have a tough time making up the difference. All states in the Democratic race award their delegates proportionally, meaning Clinton can keep piling up delegates even in states she loses.
The three states holding Democratic contests on Saturday had a total of 109 delegates at stake. The early estimates were that Clinton, who appeared headed to a smashing nearly 50-point win in Louisiana, had won at least 48 delegates on Tuesday and Sanders 37.
