Spin it anyway you like...but here are excerpts from those articles you ignored:

"'The man [Kerry] certainly has a lot on his plate,' Plazonja [executive director of the Massachusetts 9/11 Fund] said. 'In spite of all he has going on, he made it here - and most people appreciated that.'"

"'He [Kerry] showed he cared by coming, it takes a lot of effort for the people who guard him now,' said Retik, who's son, David, died aboard Flight 11 in the attacks. 'I don't think he was looking for any political advantage at all.'"

"He [Bush]worked the line at a steady campaign pace, smiling, nodding and signing autographs until Prince spoke..."

Frankly, the Bush episode sounds more like he was the one taking advantage of 9/11 for a campaign moment.
