Lets face facts: Jeremy Corbyn did much better than anyone expected, but he still didn't win. If you're a Labour supporter who wants to actually govern, and not just consume socialist speeches, its also clear that Labour has to reach beyond the folks they've won so far.
Communists, radical socialists, anarchists, and other academic movement protester types are already won. Corbyn is one of their own.
Young people who want to be able to leave Britain for Europe, got those too. (With boffo turnout I must point out). They also liked Corbyn's message of free everything.
Labour also did somewhat marginally better among the disgruntled working classes with promises of sticking it to rich people. (In spite of that, Labour won Kensington!)
So that seems to be enough to get Labour back into the game, but how do they get enough to get a majority? Or, at least enough to be the largest party and therefore form a government?
Seems to me there's just one missing piece here: a chunk of the white collar middle class.
Yes, the horrible Blair people.
Face facts, Tony Blair is 3-0, and Jeremy Corbyn is 0-1. You can't get to power without some measure of people who aren't angry at everyone and don't hate the system. Despite what you all might think, this is voting. Not revolution. There are no riots, no molotov cocktails, and no armed rebellions afoot and people would not support that. Most of the public is perfectly content to settle things at the ballot box peacefully. That is because they are content, not angry.
Fist in the air, speak truth to power type people should give Corbyn some room to moderate the message to appeal to that last little bit needed for the win. Give the man room to maneuver. Don't castigate him for it either. Because as Corbyn sits back down on the opposition bench, if there isn't going to be a five year wait, and a dozen years of Tory Government, he has broaden his appeal. His hardcore supporters should trust him and let him.
