What is the difference between campaigning and governing according to Ari Melber?

According to Ari Melber, campaigning and governing require different skills, with some individuals who excel at campaigning proving incompetent at actual governance. He illustrates this through recent examples where key staff in critical areas like nuclear safety and bird flu emergency response were fired and rehired within a single day, indicating poor decision-making in leadership positions. Melber emphasizes that the governing period is inherently different from the campaign period - it's 'not going to be as fun or as interesting' but serves a more serious purpose. Unlike campaigning, which focuses on winning votes and may be more sensational, governance requires competence and stability to effectively manage important public safety projects.
