(55,894 posts)For the Democratic Party, unpledged delegate votes, also called "Superdelegate votes" are counted on the first ballot. Although some use the term "brokered convention" to refer to a convention where the outcome is decided by Superdelegate votes rather than pledged delegates alone, this is not the original sense of the term, nor has it been a commonly used definition of a "contested convention.
Under the Democratic National Convention rules, "A majority vote of the Convention's delegates shall be required to nominate the presidential candidate" and "Balloting will continue until a nominee is selected". The role of the superdelegates was established in-part to limit such conflicts and multi-rounds of voting on the convention floor, and instead allow the candidates to woo these delegates before the convention.
