From NBC's Domenico Montanaro
Per the Atlantic's Ambinder, DNC Chairman Howard Dean sent a "strongly worded letter," urging candidates to abide by the DNC's nominating selection process calendar. This comes a day after Michigan dared the DNC by moving its primary up to Jan. 15. The DNC leveled heavy sanctions against Florida on Saturday for moving its primary up to Jan. 29th, before the allowed Feb. 5th window.
"My goal as Chairman, and our objective as a Party," Dean writes, "is to structure a nominating process that adheres to rules that are clear, straightforward and published. The vast majority of states have complied with these rules."
