Calling Kerry a waffler is more effective than calling him a liberal.
It has the potential of undermining Kerry's support from the left and the middle, and forces Kerry to take stands where he'd rather be vague.
By the end Kerry will be known both as a die-hard leftist AND a corporate sell-out AND a waffler, all true of course.
Plus Bush, rather than throwing partisan grenades, can stand back and chuckle...Kerry, you say?..who know's what's up with that guy?!?
LOL...I can hear Bush saying this.
Hooyah! That's the stuff!
