With the Adam Smith Institute’s do last night and the Speccie tomorrow, party season is in full swing.  There’s lots of clashes tonight though. Guido was thinking Mitt Romney’s could be fun, but then remembered he’s a Mormon, so doubt there will be much drinking happening there. The Balls’ are having a BBQ tonight for the B-team, but Stoke Newington is a bit of a trek. Looks like it’s going to have to be Arianna’s bash at Millbank. Remember HuffPo writers, that drink tonight is all the payment you are getting…
