Mmm, that really says what Labour have so wrong.
Never seen someone so unpopular be so popular.
Rallies like that will not kick out the Tories. It's not about Corbyn's supporters going out on rallies.
Its about the majority in the Country voting labour (or more accuralely enough to give him a majority of seats)
Until they remember that ( which they has to accept under Kinnock and then Blair was elected), they will remain in the political wilderness (despite facing a really awful alternative main party)
