Nate Silver: “The Party Decides, the 2008 book by the political scientists Marty Cohen, David Karol, Hans Noel and John Zaller, has probably been both the most-cited and the most-maligned book of this election cycle… However, the book does presume that, in part because of their breadth and diversity, American political parties are strong institutions. Furthermore, it assumes that strong, highly functional parties are able to make presidential nominations that further the party’s best interest.”
“For a variety of reasons, the nomination of Donald Trump would probably not be in the best interest of the Republican Party. Such an outcome this year, which seems increasingly likely, would either imply that the book’s hypothesis was wrong all along — or that the current Republican Party is weak and dysfunctional and perhaps in the midst of a realignment.”
