The only way to accomplish this would be to point to other instances where Kerry had a position of leadership: the military and the Senate. The latter would be pointless because it's a legislative position not an executive and the fact that Kerry's still there means that most of his constituents feel as though he accurately represented them. They can try to snipe at his military record by using 527s. While they have already started this (Swift Boat Veterans For Truth) it requires trashing a multiple medal recieving veteran, something that is not only difficult, but looks really bad. Furthermore any attacks against Kerry's military record will only make people begin to compare his to Bush's. Bush didn't show up for air guard duty during the war; I think it will certainly be a mistake for Bush to start a comparison of service records. The only other way they can assault Kerry is simply because he is untried for executive power. This would be extremely difficult thought, because he has a ton more experience in Federal government affairs then Bush when he came into office.
