From Yahoo News:

Sen. John McCain’s advertising consultants have resigned from his presidential campaign, the latest in a rash of staff shake-ups in recent weeks.

McCain communications director Jill Hazelbaker on Wednesday described the departure of Russ Schriefer and Stuart Stevens as amicable and said the Arizona Republican “appreciates their service” but accepted their resignations when they were offered Monday night.

Schriefer and Stevens were part of George W. Bush’s campaign team in 2000 and 2004 and were part of Bob Dole’s 1996 presidential campaign. The Wall Street Journal first reported the departures Wednesday night.

Aides downplayed their departure as a sign of a troubled campaign that has struggled financially and has been hit hard by the senator’s support for the unpopular war in Iraq and the failed immigration reforms.

McCain is trying to reassemble his staff and his candidacy after a disastrous six months of weak fundraising and dropping poll numbers.

McCain’s campaign manager Terry Nelson and his longtime political adviser Jon Weaver resigned earlier this month. The campaign reported ending the second quarter of the year with $3.2 million cash on hand and $1.8 million in debts. Several campaign consultants and vendors are owed money.
