I don't think it'd make any sense politically anyway.  Why would anybody want to play ball with the Lib-Dems when they've anchored themselves so nicely to the Tories?  They've already been cut in half in the polls since the election, and I suspect Labour -- which isn't that far back of the Tories as it is -- will be in a stronger position once the cuts start to hit people.

Be nice to America. Or we'll bring democracy to your country.
