"Allen is going to use it, if need be, in Virginia"
No Allen will obliterate whatever road-kill the Democrats send up against him in 2006, and Virginia is not really a protectionist state, so being somewhat anti-free trade wouldn't help Allen much in his Senate race even if he had a strong opponent.
He may want a couple of things on his record to show he is not a knee jerk free trader, though his record is overwhelmingly pro-free trade.
