OPINION: I want to make something crystal clear: House Speaker Mike Johnson is doing an excellent job. Lately, far too many people — with no real knowledge about or experience in leading Congress — have had too many criticisms. As a former speaker, I assure you they have no idea how complicated the job really is. Mr. Johnson has the most challenging speakership since the Civil War over 150 years ago. Let’s be honest. Mr. Johnson has a nominal Republican majority for organizational purposes.
