Democrats on Tuesday nominated Hillary Clinton for president, but a delegate supporting Bernie Sanders said he takes solace in the progressive agenda that is reshaping the party.

Jamie Eldridge, a Massachusetts state senator, said Sanders’ efforts have reshaped the party’s platform into one of the most progressive in modern history.

It calls for a $15 per hour federal minimum wage, overturning the U.S. Supreme Court’s Citizens United decision that liberalized campaign finance laws, and aiming for debt-free higher education.

In a telephone interview on Tuesday afternoon, Eldridge said the platform should lead Sanders supporters to back Clinton and continue the movement that the Vermont senator started.

Eldridge said he will support Clinton in the general election.

“I completely acknowledge that with Republicans in power in Congress, unfortunately a lot of legislation (Democrats) espouse will be very difficult to pass over the next couple of years,” he said.

“But part of being an advocate or concerned citizen is the recognition that things don’t come easy. We need to struggle and engage in conversation … get engaged in that process, or on the back end, work for candidates you believe in and get them elected.”

During a convention speech Monday night, Sanders urged that “any objective observer will conclude that – based on her ideas and her leadership – Hillary Clinton must become the next president of the United States.”

He omitted the next line, which appeared in his prepared statements, “The choice is not even close.” Whether he skipped the line to pause for an eruption of cheers and jeers at his endorsement of Clinton, or because he wanted to change his message, isn’t known.

Earlier in the day, Sanders was booed at his own event when he called upon supporters to get behind Clinton.

But without continued efforts to push progressive policies, Eldridge said Sanders’ successes will be for nothing.

“The movement for reaching the goals Sen. Sanders highlighted, they don’t end this week, and they don’t end in November. It’s a longer term progressive movement,” he said.

For all Democrats, the stakes of bringing along Sanders’ supporters are high. In the days after the Republican convention, GOP nominee Donald Trump received a six-point bump in the polls, and some show him now leading Clinton.

“We’re not always going to agree, but this election is very critical considering how conservative the Republican nominee is,” Eldridge said. “It’s important to get behind and help elect Clinton.”
