Never mind all the IRA links, I don't think he needs those problems because the ones of his personality (or lack thereof) are enough without any of that stuff.
Added to which he's got bloody Diane Abbott - she's tapped!! She's completely incompetent - many of the Tory cabinet may also be incompetent but at least they give an impression of knowing what they're doing!
He looks like a grumpy old man with a sour face, no charisma, no presence, not a leader.
I suspect he's a jolly nice fella and I applaud some of the general thoughts he seems to have of supporting the poor not the rich, but he's just not a leader and sadly, that is really important. People are responding to Mrs May because she's strong and has obvious direction (even though that direction may be totally wrong).
As we see from Trump, a leader can be a total bell end but if they are strong and have conviction, they get (rightly or wrongly) voted in to lead - not people like Corbyn. And I don't think you have to be a Trump, a May, a Thatcher or a Clinton, really non-aggressive yet intelligent people can also lead in that quieter more considered way eg Justin Trudeau of Canada. Plus he's got a gorgeous bottom which Corbyn cannot compete with
