Did the Democratic rules for delegate allocation cost Hillary Clinton the Democratic nomination in 2008? Did these same rules prolong the contest, creating further division within the Democratic Party? I address these two questions by “re-running" the 2008 Democratic primaries under a different set of delegate allocation rules—the ones used in the Republican nominating contest. Under these rules, Hillary Clinton would have held a four-delegate advantage at the end of the primaries and caucuses. The race would then have been decided by delegates selected at state conventions and by the Republican version of “super-delegates." So while Clinton would have benefitted under Republican rules, the use of these rules would not have given her the nomination. And Republican rules would have produced a more prolonged and divisive contest for the Democratic nomination.
