We should never, ever underestimate Boris. Underneath all that Laurel and Hardy act lies a well educated, highly intelligent, scheming politician. He is certainly the best leader that the Tory Party doesn't have..........yet. He is biding his time because he knows that all comes to he that waits.
Talking of balls, if the Tories were to ditch Dave in favour of Boris, their chances of an outright majority in May 2015 would be greatly increased. They won't do that of course, because of the lack of the aforementioned testicles.
But Boris is still young and he knows that he will have plenty of chances in the future. He is in a well paid, highly prominent job, that thrusts him into the limelight on a daily basis and he is happy to wait in the wings for a while yet.
Ignore Boris at your peril !
