Congressional Democrats from Michigan and Florida are questioning national party's handing of the presidential primary schedule dispute.
They've asked Democratic Chairman Howard Dean why he hasn't threatened to punish New Hampshire for moving up its primary while their states face loss of their delegates.
The letter says Florida got threats months before state Democrats said they'd select presidential delegates during the January 29 primary.
Florida's Republican governor and Legislature set the date.
The national Democratic party has said Michigan will lose its delegates if state Democrats use the new January 15 primary to pick delegates.
