The Florida and Michigan frontloading in 2008 is part of the progression of the general frontloading trend. It wasn't inevitable that either state would violate the "window rule" (period within which states could hold their nominating contests) of either party. In the post-reform era, states that wanted to move, moved to dates that fell within the window. The decision by the DNC to allow South Carolina and Nevada to move into the pre-window period, though, triggered a resumption of an age-old conflict in American history: small states vs. big states. So while the DNC's intent was to bring more diversity into the opening contests, they once again got some unintended consequences out of the changes (All you have to do is look at frontloading as an example of one of the DNC's post-reform, unintended consequences.).
