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.
