Well, Corbyn didn't play the game correctly. He was supposed to be the next victim for the Tory guillotine, eccentric nutter on his allotment, with mad Marxist ideas, crushed in an election, and Labour reduced to rubble.
Quite fascinating that he seemed to break out of this mould, and energized some voters.
But the Tories will set many traps for him in the next few months, hoping to reveal him as, well, a Marxist nutter. So on BBC pay, he is a bit naive.
I've no idea how this will work out. Predictions are for fools today.
