Sharon McMahon, America's Government Teacher

America’s Government Teacher

Facts Don’t Require YourApproval

Sharon McMahon spent years teaching government, history, and law to teenagers — now millions of adults show up voluntarily, without their moms forcing them to go. Her books, The Small and the Mighty and We Are Mighty, are both #1 New York Times bestsellers, and she’s the editor-in-chief of The Preamble, a newsletter read by members of Congress and college students alike.

Her fans named themselves Governerds. (She had no say in that.)

From the Author

A note from Sharon

The dedication of this book reads: "For my children, and for yours." I meant it literally. I've been carrying the stories of these twelve Americans around for years, telling them at dinner tables and on long car rides, because I wanted my kids to grow up knowing them.

Now the stories are a book, and they can travel further than my voice can. Read it with a child you love. You'll both remember it.

— Sharon
