For two years, the Republican Pennridge School Board, north of Philadelphia, governed with a burst of ideological energy. It instituted book bans and curriculum rewrites — the sort of politics pushed nationwide by Moms for Liberty, the conservative advocacy group allied with Donald J. Trump.

But in this closely divided community, the board’s moves created a backlash.

A slate of Democrats swept school board elections. They promised to put “Pennridge over politics” and end an era of drama and division for this community.

Still, a year later, the legacy of the district’s Moms for Liberty moment has not at all been undone.

Some removed books have been restored to library shelves, but others have not. Transgender students can use some bathrooms that align to their gender identities — but not all of them.
