As opposed to 2016, when Trump won a shock upset over Hillary Clinton, he and his allies have planned for years to retake the White House this January. And this time, they have stacks of policy plans.

None are so thorough as Project 2025, a 900-page conservative road map for Trump’s second term that represents a far-right wish list for Christian nationalists and corporate interests. The document lays out priorities for every corner of the government, from the Justice Department to the Environmental Protection Agency.

HuffPost's National Desk has taken a look at what Project 2025 says about major policy issues, and what it could mean for the next four years.

Government Agencies

One key section of Project 2025 applies to the entire executive branch: Trump’s plan to purge the government of civil servants who aren’t loyal to him.

Trump pursued this purge in his first term, issuing an executive order that would create a category called “Schedule F” in the federal workforce. The classification strips employment protections for the civil servants who typically serve across multiple administrations, allowing them to be fired for any reason and with little recourse. Trump ran out of time to implement the order in his first term, but he has promised to bring it back.

The effects could be dramatic, as academics, federal employees and union representatives previously told HuffPost. In addition to potentially leading to tens of thousands of federal workers losing their jobs — and being replaced by Trump loyalists — the initiative would likely create a “chilling” effect, federal employees say, and inspire both self-censorship and a worsening of work quality, the product of civil servants distracted with concerns about keeping their jobs. A wave of “brain drain” — both early retirements and forced departures — is just the start of federal employee unions’ concerns.

The Justice Department

Trump has said he would be a dictator on “day one” and use his office to “go after” the people who have prosecuted him. He declared he would kick special counsel Jack Smith out of the country in “two seconds” and commute or pardon Jan. 6 rioters — a promise he doubled down on while also proposing the appointment of a task force to review cases of Jan. 6 defendants he calls “political prisoners.” He has threatened to jail his adversaries.

Education

Under Project 2025’s plan, the federal government would no longer provide funding for education programs. Instead, education would be turned over to the states and funding would be done through education savings accounts, funded by local taxpayers. Parents would be given money, and could then choose to use those resources for public schools, religious schools, or any other alternative schools. Some states already provide public money to parents to send their children to alternative schools, and the experiment has caused massive budget shortfalls.

Health Care

Project 2025 presents a recipe for some substantial, even radical, changes to cherished health care programs, including Medicare and Medicaid.

The most visible change to Medicare would be a reversal of a signature Biden-era policy shift. Thanks to the Inflation Reduction Act, the Democratic legislation that became law in 2022, the federal government now has the power to negotiate directly with manufacturers over the prices of certain high-cost drugs in Medicare. Project 2025 calls for taking that power away.

The result would be a freer hand for drugmakers to set prices — and, almost surely, higher drug costs for seniors and people with disabilities on Medicare.

LGBTQ+ Rights

A second Trump presidency will have devastating impacts for LGBTQ+ people from day one, and Project 2025 lays out a road map that takes many state anti-LGBTQ laws to the federal level. The plan envisions a government that undermines the rights of same-sex married couples, denies the existence of trans people, and makes it more difficult for LGBTQ+ Americans to access health care and other services.
