Numerous celebrities have announced that they’re thinking about running for president in 2020. Each candidate for president has a list of preferences for vice president; similarly, each candidate for vice president has a list of preferences for president.

A stable candidacy is one where any two presidents wouldn’t try to swap vice presidents. For example, if President A is matched with Vice President A and President B is matched with Vice President B, but President A prefers Vice President B and President B prefers Vice President A, this is not a stable candidacy.

Here are the candidates for the two positions and their preferences:

President Preferences
The Rock: Moana, Ellen, Scott, Kanye, Tom Hanks
Oprah: Ellen, Kanye, Moana, Tom Hanks, Scott
Will Smith: Kanye, Ellen, Moana, Tom Hanks, Scott
Kanye: Kanye, Tom Hanks, Scott, Moana, Ellen
Po-Shen Loh: Kanye, Ellen, Tom Hanks, Scott, Moana

Vice President Preferences
Kanye: Kanye, The Rock, Po-Shen Loh, Will Smith, Oprah
Scott: Kanye, Po-Shen Loh, Oprah, Will Smith, The Rock
