Reuters seems to be of the opinion that it's more anti-Bush than pro-Kerry:
...among supporters, Kerry's greatest appeal is still that he is not George W. Bush. Whether that is enough to win a close election is unclear.
"It is anybody but Bush," Diane Cromer, a resident of Lake Worth, Florida, said after attending a recent Kerry town hall meeting.
Kerry, who raked in $54 million in the first three months and launched a lucrative fund-raising tour, acknowledges he still has a lot of work to do with swing voters. He debuted a new series of ads on Wednesday to begin introducing himself.
"A lot of people still don't really know who I am," Kerry told Democrats at a New York fund-raiser. "The level of communication that we still need to undertake here is enormous."
