Can Lauren Name All Of The U.S. Presidents In Order?

Lauren claims that at one point in her life, she could name all of the U.S. Presidents in order. She's a big history buff and had a teacher require her students to memorize all of them. In honor of President's Day, we decided to put her on the spot and see what she can do.

Surprisingly, she remembers the Presidents from the 18 & 19th century quite well, but struggled a bit when she got to recent history.
