WHEREAS, Over a year ago, the Democratic National Committee established a 2008 nominating calendar;
WHEREAS, this calendar honors the racial, ethnic, economic and geographic diversity of our party and our country;
WHEREAS, the DNC also honored the traditional role of retail politics early in the nominating process, to insure that money alone will not determine our presidential nominee;
WHEREAS, it is the desire of Presidential campaigns, the DNC,the states and the American people to bring finality, predictability and common sense to the nominating calendar.
THEREFORE, I _______________, Democratic Candidate for President, pledge I shall 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, as “campaigning” is defined by rules and regulations of the DNC.
Hillary, Obama and Edwards all agreed to the pledge on September 1, 2007.

PORTSMOUTH, N.H., Sept. 1 — Three of the major Democratic presidential candidates on Saturday pledged not to campaign in Florida, Michigan and other states trying to leapfrog the 2008 primary calendar, a move that solidified the importance of the opening contests of Iowa and New Hampshire.
Hours after Senator Barack Obama of Illinois and former Senator John Edwards of North Carolina agreed to sign a loyalty pledge put forward by party officials in Iowa, New Hampshire, Nevada and South Carolina, Senator Hillary Rodham Clinton of New York followed suit. The decision seemed to dash any hopes of Mrs. Clinton relying on a strong showing in Florida as a springboard to the nomination.
“We believe Iowa, New Hampshire, Nevada and South Carolina play a unique and special role in the nominating process,” Patti Solis Doyle, the Clinton campaign manager, said in a statement.
