“The answers are a bit complicated because Project 2025 encompasses a lot of different things (and there are some claims about what’s in it that are simply false). I think of its agenda as falling into three buckets:
1) Concentrating power in the presidency: The idea here is to give Trump and his appointees more power over the executive branch relative to permanent nonpartisan civil service professionals (who he disparages as the so-called “deep state”). Critics fear this will lead to the abuse of power and political hackery. Trump supports these ideas and we have every reason to believe he’d implement them.
2) Achieving longtime conservative priorities: This is stuff like slashing regulations, reducing federal spending on the poor, ditching efforts to fight climate change, ramping up military spending, and so on. Many progressives think these ideas are terrible, but they aren’t exactly new. Trump supports basically all of these. (Project 2025 mostly avoids taking firm positions on issues where Trump breaks from the conservative consensus, such as trade.)
3) Taking a hardline religious-right agenda: The project lays out quite aggressive proposals to use federal power to prevent abortions and restrict certain contraceptive coverage. It even says that pornography should be “outlawed” and its creators and distributors should be “imprisoned.””
