Labour’s performance in polls and in mid-term elections has become a political football – not just the usual rather routine spinning of parties saying how well they are doing, but a key faultline in Labour’s internal leadership battle. A key argument of Jeremy Corbyn’s critics is that he is an electoral liability – therefore they highlight anything suggesting that Labour are doing badly. In contrast Jeremy Corbyn’s supporters brandish anything that can be presented as a sign that Labour are actually doing well.
Which side is right? A lot of what both sides say is exaggerated or unfair. Some of it is just downright untrue. For what it’s worth, this is an attempt to unpick the evidence and look at it as fairly as I can. I expect, therefore, that this piece will not make anyone happy. It’s not going to say that Labour polls are the worst for any party ever, nor that Jeremy Corbyn is actually the messiah. It’s also quite long, so if you’re hoping for either of those conclusions, perhaps give it a skip.
