Who are they (from the UK Guardian)
Progressive groups are preparing a concerted fightback against Donald Trump and Project 2025, the vast far-right policy plan, sponsored by the Heritage Foundation, which promises slashing reform to all areas of government when the president-elect returns to power next month.
Skye Perryman, chief executive of Democracy Forward, a national legal organization, will help lead that fightback via Democracy 2025, a new coalition of litigation, advocacy and policy groups designed to deploy swift legal defenses an effort informed by, but meant to be stronger than, the scramble Trump prompted in 2017, the year Democracy Forward formed.
