“If he continues to declare his full faith in the Democratic Party, it will leave many of his supporters very disappointed,” she said. “That political movement is going to go on – it isn’t going to bury itself in the graveyard alongside Hillary Clinton.”
In a video message to supporters, Sanders said he would continue his “political revolution” to change the Democratic Party.
“This campaign has never been about any single candidate. It is always about transforming America,” he said.
Sanders, an independent senator from Vermont, has a long list of agenda items, including the ouster of Democratic National Committee chairwoman Debbie Wasserman Schultz, overhauling a primary process that would make it easier for people to vote, and an end to superdelegates, the leaders unbound by their state’s results and a liberal platform that provides help for middle- and lower-income people.
