Meanwhile, Michigan moved its primary to January 15, 2008, also in violation of party rules. In October 2007, Obama, Richardson, Biden, and Edwards withdrew their names from the Michigan primary ballot, under pressure from the DNC and voters in Iowa and New Hampshire. Kucinich unsuccessfully sought to remove his name from the ballot, whereas Clinton and Dodd opted to remain on the ballot. In December 2007, the DNC ruled that Michigan's 128 pledged delegates and 29 superdelegates would not count in the nominating contest unless it were held on a later date. The Michigan Democratic party responded with a press release noting that the primary would proceed with Clinton, Dodd, Gravel, and Kucinich on the ballot. Supporters of Biden, Edwards, Richardson, and Obama were urged to vote "uncommitted" instead of writing in their candidates' names because write-in votes for those candidates would not be counted.
