Michigan ? Michigan Democrats are not going to hold a do-over presidential primary.

The state party’s executive committee made it official Friday, saying “it is not practical” to conduct a party-run primary or caucus as a way to get the state’s delegates seated at the Democratic National Convention this August in Denver.

Michigan and Florida were stripped of their convention delegates for moving up their primaries before Feb. 5 in defiance of party rules. Florida Democrats already had decided against holding a second primary election.

Presidential hopeful Sen. Hillary Rodham Clinton won the Jan. 15 Michigan primary. Rival Sen. Barack Obama had pulled his name from the ballot. Many of his supporters voted for uncommitted, which got 40 percent of the vote.

Michigan Democrats hope the campaigns can agree on a way to split Michigan’s delegates so they can be seated at the convention.
