The theme of the Democratic convention seems to be that John Kerry is qualified to be president because he spent four months in Viet Nam.   This is completely ridiculous.  But assume it's true.  If so, isn't what Kerry did in Viet Nam a legitimate campaign issue?  According to these veterans, Kerry's service actually disqualifies him for the presidency.  More can be found here.  To say the least, this presents Kerry's service in a less-than-heroic light.  If Kerry's Viet Nam experience is all he's got - and according to the convention it pretty much is - he is manifestly unqualified for the presidency.
