Should Kerry just stay on vacation?

[Swing low, sweet chariot. Comin' for to carry me home.]

I'm beginning to believe Kerry's negativity rating will continue to climb each time he opens his mouth.  Maybe his chances of winning in Nov would be better if he simply remained on vacation.  

Probably wouldn't help though, he has continued to lose his temper and make dumb comments even on vacation.  And the appearance of his body on top of a snowboard hasn't help.
