Shays shuffle

It never amazes me what the suits in Washington will do to get re-elected.
Case in point Rep. Christopher Shays (R-Conn.) long time backer of the War and now conveniently calling for a timetable for withdrawal.
Is it acceptable to call him a waffler now, or a flip-flopper or whatever the opposition would like to label him?
It is too bad as noted in the article that his change of thought required 14 trips and 3 years to notice that the Iraq situation has not made the progress the administration was so optimistically hoping for.
So it goes.
