I doubt it. His health is overshadowing Kerry more than Bush. In fact, right now it's having a demoralizing effect on left-leaning swing voters and Democrat voters alike.
About all we're seeing right now is that Bill Clinton can completely eclipse John F'n Kerry without trying.
Now if he makes an incredibly speedy recovery and hits the campaign trail to get his voter base to vote John Kerry out of loyalty to HIM (he'd be implying his days are numbered) then the questions of timing will cease to be jokes and become extremely valid questions.
Good point. If Clinton is seen on the campaign trail..any time in the remaining two months of the campaign....people are going to wonder.
