I'm probably closer to Corbyn's views than I am to any Tory and 90% of the LibDems, but:
He opposes arming Ukraine, whether through pacifism or being pro Putin he hasn't made clear;
He was wishy washy over Brexit and his failure when Labour leader to go all out against it certainly contributed to the 'Leave' vote;
He was churlish over the anti semitic controversy and again left a sour taste when he could have come out clearly against it in the party and apologised for past mistakes, but wouldn't.
For those reasons, he can feck off as far as I'm concerned. He can always stand as an independent.
