Beginning on Thursday, Mitt Romney will have the company and protection of the Secret Service, campaign sources told ABC News. "The Secret Service is charged with protecting presidential candidates in addition to the president himself, and providing protection to a candidate before he secures a nomination has become fairly common." Lest you think Romney has been walking around unattended, his campaign has traveled with private security until now. No specific threat prompted the change that was floated after the New Hampshire primary but increased crowd sizes have raised concerns, so the Service will step in. Being the front-runner has its perks. But can Romney fire these people?
