Because he is different, certainly.
Have a quick comparison of Jeremy Corbyn’s voting pattern in Parliament with that of rest of Labour leader candidates at http://www.theyworkforyou.com/mps; you will agree.
Along with these points, one need to read following Corbyn statements:
“I don’t reply to personal abuse, to personal attacks, to personal criticism because the policies are more important, the issues are more important” – in response to collective abuse and constant criticism from Tony Blair and his ‘new-Labour’ followers. Btw, why is Blair so worried about a Corbyn-led Labour? Just read #1 !
#5 and the last one in the list are good enough indications on how Labour could transform under Corbyn.
What if Corbyn Wins?
Blairite Labour leaders are prophesying doom under a future Corbyn leadership; this itself will be the first issue for Corbyn to tackle, if he wins the contest. Though it appears Corbyn has support at grass-root level, he need to integrate the party and ensure that the the party, its leadership and Parliamentary representatives talk the talk and walk the walk the walk – together.
One thing is sure; results of 12th Sept will be just the first-half of what’s in store in coming years for an internally-divided Labour party.
