Well, there is some (very liberal) action being taken to prevent it. Basically, there is a large congressional task force trying to figure out how to prevent Project 2025 from being implemented and also another focused on trying to prevent/challenge the sweeping presidential immunity granted by the supreme court 2 weeks ago. They've proposed a constitutional amendment to specifically state that the president does not have criminal immunity and have plans to prevent actions being taken/generally be obstructionist.

Now, the obvious problems are 1) you have to keep "stopping project 2025" every 4 years, and as soon as a Republican gets into office - boom, it's done. 2) constitutional amendments require 2/3 majority votes in the House and Senate to pass - and Dems will never have a 2/3 majority, and the vote will be on party lines. 3) as soon as it is implemented, the changes will all be made legal - the fascists will shape the gov't around them as soon as they gain power, that's the whole point of what project 2025 is.
