As the head of a small, divided, and unruly majority party, Mike Johnson, like Kevin McCarthy before him, had an extremely difficult job. Even so, by any reasonable standard, he has been a failure. Why?
Because Johnson viewed the House of Representatives as an appendage of the Trump administration instead of a co-equal branch of government with interests that will exist long after Trump is gone. As a result, if Trump failed, so did he. And that is exactly what happened.
