Having begun their first determining step in Stage III in 2008 (Tuesday 3 June 2008), Montana receives a 10% Bonus in district and at-large delegate votes (+0 district and +1 at-large). Total delegate votes changed from 23 to 24.

Tuesday 3 June 2008: 16 of 25 delegates to the Democratic National Convention are allocated to presidential contenders based on the results of the voting in today's Montana Presidential Primary. A mandatory 15 percent threshold is required in order for a presidential contender to be allocated National Convention delegates at either the congressional district or statewide level.

• 10 district delegates are to be allocated proportionally to presidential contenders based on the results of the primary. For the purposes of electing delegates, Montana's single congressional district is divided into an Eastern-District and a Western District with each district choosing 5 delegates.
• The Western district consists of Montana's "old 1980 CD 1" (when Montana had 2 Congressional districts). The region includes: Beaverhead, Broadwater, Silver Bow, Deer Lodge, Flathead, Gallatin, Glacier, Granite, Jefferson, Lake, Lewis and Clark, Lincoln, Madison, Mineral, Missoula, Park, Powell, Ravalli, and Sanders counties.
• The Eastern district consists of Montana's "old 1980 CD 2" (when Montana had 2 Congressional districts). The region includes: Big Horn, Blaine, Carbon, Carter, Cascade, Chouteau, Custer, Daniels, Dawson, Fallon, Fergus, Garfield, Golden Valley, Hill, Judith Basin, Liberty, McCone, Meagher, Musselshell, Petroleum, Phillips, Pondera, Powder River, Prairie, Richland, Roosevelt, Rosebud, Sheridan, Stillwater, Sweet Grass, Teton, Toole, Treasure, Valley, Wheatland, Wibaux, and Yellowstone counties.
• In addition, 6 delegates are to be allocated to presidential contenders based on the primary vote statewide.
  • 4 at-large National Convention delegates
  • 2 Pledged PLEOs

Here is how we compute the delegate count:

1. A candidate must receive 15% or more of the total popular vote to qualify for delegates. Discard votes cast for those candidates who do not qualify.
2. Allocate Congressional District delegates from the qualified vote in each district. Allocate Pledged PLEO and At-Large delegates using the state-wide qualified vote.
3. In each jurisdiction (CD and statewide):
1. Total qualified vote = total votes cast for the qualifying candidates in the jurisdiction.
2. Allocation = (delegates for the jurisdiction) × (candidate's popular vote) ÷ (total qualified vote).
3. Assign each candidate the WHOLE NUMBER of delegates.
4. If delegates remain, allocate each of the remaining delegates to those candidates with the LARGEST REMAINDERS.

Sunday 8 June 2008: State Convention

The remaining 9 National Convention delegates consist of

• 8 Unpledged PLEO delegates:
• 5 Democratic National Committee members.
• 2 Members of Congress (2 Senators and 0 Representatives).
• 1 Governor.
• 0 Distinguished Party Leaders.
• 1 Unpledged "add-on" (selected during the State Convention).

These 9 delegates and will go to the Democratic National Convention officially "Unpledged".
