The position of “Second in Command” is often filled by a jerk in real life. Some years ago I came up with my “Assistant Manager Theory”, based on my observations at several different jobs:
The General Manager is in charge. He knows he’s in charge, and you know he’s in charge, and he knows that you know he’s in charge.
The Assistant Manager is in charge. He knows he’s in charge, and you know he’s in charge, but he’s worried that you don’t think he’s in charge.
Therefore, the General Manager is easier to work with / get along with, because there’s no misunderstanding about who’s in charge. Meanwhile, the Assistant Manager can come off as a jerk, because his doubts about whether you know he’s in charge compel him to constantly remind you that he’s in charge. So he will exercise his authority for no reason other than exercising it. For example, assigning trivial, non-essential tasks simply because he can - he’s telling you to do it because he can tell you to do it.
And really, from the average American’s perspective, the Vice President is the ultimate Assistant Manager.

Gerald Ford
Spiro Agnew
Hubert Humphrey
Lyndon Johnson
Richard Nixon

Harry Truman
Henry(?) Wallace
Aaand before that it starts to get hazy.
In 2012 he was the Chief of Staff, not veep. In addition to what’s been posted I’ll add the *danger from an unexpected source *(the butler did it), trope.
Where I’ve worked, the General Manager always got to play “good cop”, while the Assistant Manager always had to play “bad cop”. The GM would hand out raises and bonuses, while the AM would be the one to tell people to quit goofing off.
