Mar. 20 - With the race between Senators Hillary Clinton and Barack Obama becoming tighter by the day -- settling the controversy over votes in Michigan and Florida may be crucial for who becomes the Democratic nominee. Obama -- whose name was not on the original ballot in Michigan -- holds over a 150 delegate lead in the overall race, and has remained relatively silent on the issue.

Michigan Party leaders say the proposal to hold a revote is stalled and unlikely to be approved before this week's deadline. Florida Democrats have all but abandoned efforts to vote again.
