2008 Michigan Democratic presidential primary

The 2008 Michigan Democratic presidential primary took place January 15, 2008. Originally, the state had 156 delegates up for grabs that were to be awarded in the following way: 83 delegates were to be awarded based on the winner in each of Michigan's 15 congressional districts while an additional 45 delegates were to be awarded to the statewide winner. Twenty-eight unpledged delegates, known as superdelegates, were initially able to cast their votes at the Democratic National Convention in Denver, Colorado.

However, the Democratic National Committee determined that the date of the Michigan Democratic Primary violated the party rules and ultimately decided to sanction the state, stripping all 156 delegates and refusing to seat them at the convention. Despite this, the Michigan Supreme Court ruled that the primary could go ahead as scheduled. The DNC Rules and Bylaws Committee later met on May 31, 2008, and agreed to seat all of Michigan's delegates with each delegate receiving half of a vote. As a result of this compromise, Michigan had 78 votes at the convention. On August 24, the delegates had full voting rights restored.
