A day after admitting “it doesn’t appear” that he is going to be the Democratic nominee for president, Vermont Sen. Bernie Sanders released a detailed op-ed outlining the changes he hopes his campaign inspires.

Writing for the Washington Post, Sanders said the question isn’t about his goals, but those of “the 12 million Americans who voted for a political revolution,” laying out many of the arguments that propelled his campaign through a political process that seemed all but wrapped up before he even entered.

“The current campaign finance system is corrupt. Billionaires and powerful corporations are now, through super PACs, able to spend as much money as they want to buy elections and elect candidates who represent their interests, not the American people,” Sanders wrote. “Meanwhile, we have one of the lowest voter turnout rates of any major country on earth, and Republican governors are working overtime to suppress the vote and make it harder for poor people, people of color, seniors and young people to vote.”

Sanders called for overturning the Citizen’s United decision, universal voter registration, criminal justice reform, and making a concerted effort to address climate change.

The op-ed comes several weeks after rival Hillary Clinton wrapped up enough delegates to become the Democratic party’s presumptive nominee. Sanders has yet to formally endorse Clinton, but vowed to “do everything in [his] power” to stop presumptive Republican nominee Donald Trump. The Vermont senator said Wednesday that he “personally" intends to begin his role defeating Trump “in a very short period of time.”

Before heading to bat for the Clinton camp, however, Sanders said he continues to negotiate “almost every day with the Clinton people" about how best to incorporate his supporters’ goals into the party platform, using the leverage produced by his energetic campaign to ensure Clinton promises to support more progressive causes.

“What do we want? We want to end the rapid movement that we are currently experiencing toward oligarchic control of our economic and political life,” Sanders concluded. “As Lincoln put it at Gettysburg, we want a government of the people, by the people and for the people. That is what we want, and that is what we will continue fighting for.”
