The Michigan Democratic Party executive committee announced today that holding a second primary or caucus to ensure the state's delegates are seated at the Democratic National Convention is "not practical," ending any hope of a re-vote.

Here is the release:

The Michigan Democratic Party has carefully reviewed several proposals for a Party-run primary or caucus as a means of resolving the dispute over the seating of the Michigan delegation to the 2008 Democratic National Convention. We have concluded that it is not practical to conduct such a primary or caucus. We will continue to work with the Working Group, the DNC and the candidates to resolve this matter in a manner which is respectful of the views of Democrats in Michigan, and which is fair to those who voted in the January 15th Democratic primary.
