The Maine Democratic Party reports 43,866 total attendees in their caucuses.

Here is how we estimate the delegate count (Based on complete 10 February 2008 Municipal Caucus results obtain from a party source on 15 April 2008. Note that no National Convention delegates are allocated until the Saturday 31 May 2008 State Convention.):

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. Clinton and Obama have qualified for delegates.
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.
