2008 Vermont Democratic presidential primary

The 2008 Vermont Democratic presidential primary was an open primary that took place on March 4, 2008. Barack Obama won the primary, his only decisive win among the four March 4 contests. The primary determined the 15 pledged delegates that represented Vermont at the 2008 Democratic National Convention. The delegates were awarded to the candidates, Obama and Hillary Clinton, on a proportional basis. Vermont also sent 8 unpledged "superdelegates", to the convention not bound by the results of the primary.

Delegate breakdown
The Vermont Democratic Party sent 23 total delegates to the 2008 Democratic National Convention. Of those delegates, 15 were pledged and 8 were unpledged. The 15 pledged delegates were allocated (pledged) to vote for a particular candidate at the National Convention according to the results of Vermont's Democratic primary on March 4. The 8 unpledged delegates (popularly called "superdelegates" because their votes represented their personal decisions rather than the collective decision of many voters) were free to vote for any candidate at the National Convention and were selected by the Vermont Democratic Party's officials.

The 15 pledged delegates were further divided into 10 district delegates and 5 statewide delegates. The 10 district delegates represented Vermont's single Congressional District. The 5 statewide delegates were divided into 3 at-large delegates and 2 Party Leaders and Elected Officials (abbreviated PLEOs).

Of the 8 unpledged delegates, 7 were selected in advance and 1 was selected at the Vermont Democratic Party's National Convention Delegate Meeting on June 7. The delegates selected in advance were 5 Democratic National Committee members, U.S. Representative from Vermont Peter Welch, and U.S. Senator from Vermont Patrick Leahy.

Delegate selection process
The Vermont Democratic Party used the results of the state's presidential preference primary on March 4 to determine the allocation of delegates to each presidential candidate. Though the primary was used for allocating delegates, the delegates themselves were selected in a caucus process. On March 22, the Party held a series of town-level caucuses to select its first tier of delegates. On May 24, the Party held its state convention in which the town-level delegates selected the 10 district-level delegates to attend the 2008 Democratic National Convention. The remaining 5 pledged delegates, plus the remaining unpledged delegate, were selected at the Vermont Democratic Party's National Convention Delegate Meeting on June 7.

Polls
