Appealing to Labour voters who vote in leadership elections is not the same as being elected by the general population to be Prime Minister, by any stretch.
True, but the electoral logic that says Labour must be a centre-right party to get elected is the electoral logic of 1997, mixed with a heady selection of conscious and unconscious biases.
In reality I don't think anybody is qualified to state as fact that Corbyn is "unelectable". To me it's much more likely a statement intended to influence rather than inform.
