Being marginally left of centre, i have voted labour at one of the last 2 elections (in the other i voted tactically to try and keep the conservatives out)
Under Corbyn i will not vote labour under any circumstances. Pretty much a reflection of the polls above this post. He may well appeal to the dyed in the wool labour heartland, but that is no way near enough to win an election. Labour's vote will be reduced to it's skeletal status, and possibly pave the way for a Lib-Dem resurgence.
In that case, my politics have been broadly in line with yours, but I'm prepared to give him more of a chance. I can't get angry about his IRA conversations or not singing the national anthem. I don't particularly like the idea of income tax >50% at any level, but if he is going to up it to 70% for people earning over a million a year, I can't say it bothers me much.
It feels as if this country has become a less "just" place after decades of Tory rule and patsy centre ground Blairite career politicians with absolutely no vision. If Corbyn has ideas of how to fix this, and if he appears to be a moral person in his actions going forward, then personally I want to see more. So far I like what I see - dozens of right wing Labour no-marks are running away, as if they were ever wanted in the first place. Good stuff.
