Sorry, but they know that a 'Rat takeover of the Congress will help them, so they'll lay on an event for us, just like they did in Madrid, and for the same reason.
They actually would have done themselves more good if they could have pulled this stunt before Blair called for elections, but the British system doesn't give them much time to react. Ours does. They'll be ready to go.
You can't seriously believe that Americans will react like the cowardly Spanish, can you? Personally I believe the effect will be exactly opposite if the towel heads do such a thing.
