During a national political convention, the number of state delegates who conduct business at sessions varies by party and year, but generally:
- For the Democratic National Convention, more than 4,500 delegates convene, with the number of delegates from each state allocated based on population and voting history. These delegates are pledged proportionally to candidates based on primary or caucus results in each state, and they conduct business such as voting on the presidential nominee and party platform
- For the Republican National Convention, there are typically over 2,500 delegates. Each state sends a delegation based on party rules and state laws, and delegates vote to select the party's presidential nominee and conduct other convention business
- Additionally, some conventions like the National FFA Convention have a set number of delegates (e.g., 475) who represent their states and conduct business sessions, voting on organizational recommendations and amendments
In summary, the number of delegates conducting business at national convention sessions is in the thousands, with the Democratic convention usually having about 4,500 delegates and the Republican convention about 2,500 delegates, all representing their states and performing official convention business
