The Bush campaign's chief strategist Matthew Dowd has hit back at the ad strategy, criticising the Kerry campaign for tipping its hand early, giving Bush an early insight into Kerry's electoral strategy.
Kerry received $75m (£41.8m) in federal funds for the autumn campaign and Bush is to receive the same this week.
Separately, Kerry has ordered an overhaul of his campaign staff and has appointed two former aides of Bill Clinton to key jobs.
Joe Lockhart will take over communications strategy, while Joel Johnston will take over response operations.
The appointments are seen as a move to shake up communications strategy after the media team was criticised for failing to respond to critics of Kerry's Vietnam war record.
Yesterday, Kerry criticised Bush's record in Iraq, telling veterans that he would have done "almost everything differently".
Last month, Kerry launched a celebrity-studded ad campaign starring Hollywood A-listers Matt Damon and Scarlett Johansson. The "10 Weeks: Don't Get Mad Get Even" campaign was created by political action group MoveOn.org, with Doug Liman, the director of 'The Bourne Identity' and 'Swingers', teaming up for one commercial.
Rob Reiner, the veteran director of 'When Harry Met Sally' and 'The American President', has used a 30-second clip of a tongue-tied Bush as part of his ad, while another spot was produced by Martin Sheen, who plays Democrat president Jed Bartlett in 'The West Wing'.
