The four top Michigan Democrats spoke with officials in Sen. Hillary Clinton's campaign and Sen. Barack Obama's camp, seeking a compromise acceptable to the state party, the Democratic National Committee and both presidential campaigns, the Detroit News reported Friday.

The DNC took away Michigan's 156 national convention delegates because it held a January primary, violating party rules.

Thursday's talks centered on a state-run, privately financed primary of voters willing to declare themselves Democrats, sources told the News. A compromise may be announced soon, but details must be negotiated, including the mechanics of the party declaration, and securing legislative and gubernatorial approval to call the election.

The cost, estimated to be at least $10 million, would be secured from private financial sources, the source said.
