Ronald Reagan, 1980?
Remember "Voodoo Economics"?
I thought about Reagan-Bush, but even there it was more Party Politics. Bush had his faction, Reagan had his and they better team up if they want to win (though any bunny rabbit could have whupped Jimmy Carter in 1980). The premise on the show is that the previous president picked her to "help with the women vote." They make it sound like she wasn't even a member of the party. Too out there.
