Maybe you've forgotten about (or never learned about) the major league losers like
Neil Kinnock, Ed Milliband, Nick Clegg, John Major, Iain Duncan Smith, Michael Howard, ...?

The first two were previous Labour leaders, Clegg was allegedly a Liberal Democrat,
Major, IDS & Howard were Tory leaders. All were/are vain & greedy losers.

The Liberal Democrats are - deservedly - a non-starter these days, primarily due
to the cowardly, self-serving treachery of Clegg. No-one will trust them again for
decades.

Labour deserves to be a permanent minority party if they screw up this opportunity
to leave Blair's Conservative-Labour mongrel behind and get back to representing
the workers, the poor, the people who they have been deliberately ignoring for
countless years in favour of playing the same crony-capitalism games as the Tories.

The Tories are only in power through a) inertia and b) lack of competition.

If Corbyn is shafted before he even gets chance to clean out the champagne socialists
of the PLP, Labour will remain a bunch of squabbling, bed-wetting little non-entities.
