Political campaign staff are the group of people who formulate and implement the strategy of a political campaign. Campaign staffs are generally composed both of unpaid volunteers and paid employees of either the campaign itself or a related political party. The staff may include political consultants who provide advice and assistance to a campaign. Structure of a campaign Campaigns are generally run by a campaign manager who coordinates the campaign and assures that efforts are being focused effectively. In small local campaigns, the campaign manager will often be the only paid staff member and will be responsible for every aspect of the campaign that is not covered by the candidate or volunteers. In larger campaigns, such as a United States presidential campaign, hundreds of staff members will cover the required tasks. While campaign managers are often the lead strategists in local campaigns, in the United States larger campaigns hire consultants to serve as strategists and the campaign manager focuses mostly on coordinating the campaign staff. Campaign managers will often have deputies who oversee various aspects of the campaign at a closer level. Directly below the campaign manager on the organization chart is the deputy campaign manager and directly below them are department directors who coordinate specific aspects of the campaign. These staff members often have deputies as well. In some campaigns, an executive chairman of the campaign committee will be appointed. The responsibility of an executive chairman will vary widely by campaign, usually an executive chairman is a consultant on internal matters such as campaign staff appointments and major internal policy. Below the department level, campaigns vary widely in their structure. On larger campaigns, there will be various coordinators for certain functions within each department. For example, within the fundraising department, there might be a staff member who focuses only on direct mail fundraising. The foundation of the campaign structure are the interns and volunteers. Their tasks can include addressing envelopes, entering data into databases, and canvassing voters on behalf of the campaign.
