Why the Corbyn spy allegations made no difference to public opinion
Saturday's Times had the latest YouGov voting intention results, which were CON 40%(nc), LAB 42%(+1), LDEM 8%(nc).
It also had results from a poll asking about the media allegations about Jeremy Corbyn having met a Czech spy in the 1980s, which clearly illustrated why such things make very little difference.
To start with, most people pay very little attention to the day-to-day soap opera of politics. 40% of people said they had been completely unaware of the story until taking the survey, a further 31% said they had noticed it, but hadn't really paid it any attention. That leaves less than a third who had actually taken it in. Obviously things that no one notices have no real impact, especially since those people who do watch political news stories will disproportionately be those who are interested in politics and have firm political allegiances.
Asked if they thought the allegations were true, the results were as you'd expect. A large majority of Labour voters thought that Jeremy Corbyn probably had a perfectly innocent meeting with someone he thought was a diplomat, and that he probably didn't give any information to any Czech agents. The only people who believed it were Conservatives. This is typical of such allegations: people view them through the prism of their existing political allegiences. If it's an allegation against a party you support, you are likely to view it with scepticism and give the politician concerned the benefit of the doubt, if it's an allegation against a party you dislike then it will confirm all the negative things you thought already.
Finally, YouGov asked if the spy allegations and the way Jeremy Corbyn had responded to them had changed people's opinions of Jeremy Corbyn at all. Only 8% of people said it had made them think more negatively about him (and they were mostly Tories to begin with). 6% said it made them think better of Corbyn (and they were mostly Labour voters to begin with). A hearty 64% said it made no difference at all.
