The 2016 presidential nominating race was barely over, and already Bernie Sanders was looking ahead.

Days before the Democratic National Convention formally nominated Hillary Clinton, the Vermont senator transformed his 2016 campaign organization into Our Revolution to promote his progressive proposals, back like-minded candidates and, in essence, take over the Democratic Party.

“We have begun a political revolution to transform America, and that revolution, our revolution, continues,” Sanders told the convention, endorsing Clinton but making clear his quest to remake the Democratic Party would continue, regardless of the outcome.

Nine months later, he is well on his way to succeeding. Though his choice for party chairman narrowly lost, Sanders has moved into the leadership vacuum after Clinton’s defeat to emerge as a leading national voice against President Donald Trump.

This week, the party chair he opposed, former Labor Secretary Tom Perez, is joining with the Vermont senator on a second “come together and fight back” tour of “red” and “purple” states. The tour was to included a stop Thursday in Grand Prairie, where Minnesota Rep. Keith Ellison, the deputy chairman and a Sanders ally, was to represent Perez.

The goal, Sanders said Sunday on CNN, is to “see that the Democratic party becomes a 50-state party, a bottom up grass roots party that is prepared to stand up to the big money interests.”

The tour, similar to one last month, illustrates the degree to which the party’s national leadership is latching onto his economic message. Senate Democratic Leader Chuck Schumer and Sen. Elizabeth Warren, among others, have joined Sanders in rallies on issues from health care to immigration.

Meanwhile, in state after state, the Sanders forces are moving either to take over the existing party machinery or to set up their own state or even county organizations, Details are a bit hazy since Our Revolution was created as a non profit social welfare organization, exempt from federal disclosure rules for political action committees.

All of this means the political machine being created by the Independent Vermont senator (still not a registered Democrat) could become a strong underpinning if he decides, at age 78, to undertake a second presidential bid in 2020.

Sanders himself says it’s too early to speculate about that. But an announcement this week disclosed he’ll appear in July at the Citizens for Community Improvement’s “action convention” in Iowa, the first caucus state.

Even if Sanders doesn’t run, his organization could be an enormous asset to whomever he backed, especially if Trump’s unpopularity continues and inspires a large Democratic field.

The senator’s growing influence extends beyond the structural aspects of politics to support for his ideas.

In New York, Gov. Andrew Cuomo recently won approval of a higher education plan similar to the proposal Sanders proposed and Clinton endorsed. It provides free tuition at community and public colleges for fulltime students with family annual incomes up to $125,000, provided they agree to stay and work in the state afterwards.

And even some conservative columnists have suggested Trump’s inability to win approval of legislation to repeal and replace the Affordable Care Act will lead inevitably to a single payer plan similar to Sanders’ proposal to expand Medicare for all Americans, regardless of age.

“A broad national consensus is developing that health care is indeed a right,” Charles Krauthammer wrote last month in The Washington Post, adding that, “As Obamacare continues to unravel, it won’t take much for Democrats to abandon that Rube Goldberg wreckage and go for the simplicity and the universality of Medicare-for-all.”

Bernie Sanders may have lost in 2016, but he’s more of a factor for the Democratic Party now than the winner has been.
