Early states join forces

From NBC's Domenico Montanaro
The Iowa, Nevada, New Hampshire and South Carolina Democratic Parties have joined together to ask the presidential candidates to sign a pledge that they will "not campaign or participate in any state which schedules a presidential election primary or caucus before Feb. 5, 2008, except for the states of Iowa, Nevada, New Hampshire and South Carolina." Earlier today, we reported that DNC Chairman Howard Dean sent a letter urging the candidates to abide by the calendar.
