Since the presidential election, many Democrats and others who are deeply concerned about the incoming Trump administration have been on the defensive.

Opponents are criticizing troubling things President-elect Donald Trump or his surrogates have said, or they’re waiting to see what dangers may develop.

Those who believe that Trump poses an unprecedented threat to constitutional democracy ought to take a page from the Republican playbook. After President Barack Obama took office in 2009, Republicans advanced their own agenda, knowing full well it could not be enacted under Obama’s presidency. The Republican-controlled House amassed more than 60 symbolic votes to repeal Obamacare, for example. Notably, these votes served an important purpose as part of a larger plan to identify a clear agenda, which the Republican party stood ready to advance once it had the chance. After the 2016 election, Republicans can now move to make these plans a reality.

Democrats must create a blueprint for their own agenda — even if it cannot pass. This will serve both to focus their efforts during the Trump administration and to describe an alternative to a restrictive Trump and Republican intentions.

Trump’s own actions have also created an opportunity. As MarketWatch columnist Brett Arends has observed, Trump is betraying his core supporters by setting up a presidency designed to pad the already fat bank accounts of Trump, his family, and their wealthy friends.

“ A clear contrast to Trump’s presidency of, for, and by the Republican elite. ”

Democrats should reach out to those who voted for Trump hoping to change the system but instead see a familiar cast of characters running the show and enriching themselves at public expense. Here are three ways that Democrats can offer Americans a clear contrast to Trump’s presidency of, for, and by the Republican elite:

1. Drain the swamp — for real: Trump is filling his cabinet with Wall Street and Washington elites. Politico estimates that cabinet nominees so far could be worth as much as $35 billion — calling this ”a staggering agglomeration of wealth unprecedented in American history.”

Trump is sending a clear message that he “plans to emphasize policies friendly to Wall Street.” It’s not just Trump’s allies who are making out like bandits. Trump and his family are already cashing in on the presidency — even before he takes office, with everything from merchandizing schemes to overseas deals seeking favorable treatment by foreign governments. This suggests corruption that could rise to the level of a constitutional violation.

The script here writes itself. Democrats can position themselves as being on the side of regular Americans — although doing so will depend on rallying behind Sens. Elizabeth Warren and Bernie Sanders, Rep. Tim Ryan, and other leaders who can credibly make this case.

Americans need opposition leaders reminding them that Trump and his allies in Congress are advancing policies “heavily skewed to the most wealthy” while harming the middle- and working class. Democrats should propose measures aimed at helping ordinary Americans — including making wealthy individuals and big corporations pay their fair share of taxes, increasing the federal minimum wage, investing in infrastructure projects that will create millions of jobs, protecting and expanding Social Security and Medicare (essentially the economic policies Bernie Sanders advocated during his presidential campaign).

2. End crony capitalism and corporate welfare: Conservative commentator James Pethokoukis described Trump’s Carrier speech as the worst one he’d heard since Democratic presidential candidate Walter Mondale pledged to reverse Reaganomics in 1984. Others have observed that the deal is premised on a combination of special favors as well as executives’ desire to stay in the new administration’s good graces.

Trump’s move has drawn criticism across the political spectrum — from Sarah Palin to Bernie Sanders. Sanders observed that Carrier’s parent corporation, United Technologies Corp. US:UTX , “took Trump hostage and won.” Hundreds of Carrier employees will still lose their jobs, but the company will get a huge tax break.

The Democrats’ message, as Sanders puts it, should be this: “If Donald Trump won’t stand up for America’s working class, we must.”

That means no more corporate welfare, and no special tax breaks. In short, follow the strategy Trump himself argued for during the campaign but has now rejected.

3. Make America great — for all workers: The “working class” is more than just white men. Trump effectively used race and ethnicity to drive a wedge between voters, using blacks, Latinos, Muslims, and immigrants as scapegoats. But Trump’s presidency promises to be disastrous for the white working-class he claimed to champion.

Democrats should form a coalition of the working- and middle-class, without regard to race, ancestry, religion, or gender. Slate columnist Jamelle Bouie recently observed that Rev. Jesse Jackson’s presidential campaigns in the 1980s provide a roadmap for Democrats in 2016. Jackson practiced a politics that “ask[ed] black Americans to see that their struggle is the struggle of white workers and vice versa.” His approach, Bouie noted, “radiated outward to everyone who has struggled for dignity and recognition.”

Standing with working Americans does not mean choosing between white, black, or Latino; it does not mean empathizing with one group at the expense of another. Jackson showed it is possible to speak to all of these groups respectfully, recognizing the unique challenges each face while seeking to move all of them forward. That’s a rallying cry more than just Democrats can support.
