Hopefully - although it is probably worth remembering that there are likely two years till the next election, and it's only just over two years since Starmer took over.The phrase (as nicked off Tolmie) is;
'Tipping Point'.
Just before he took over, YouGov had a 24 point lead for the Tories, and they had a 20+ point lead in more than a dozen polls around that time. Theresa May also had a poll lead in the 20s when she called the 2017 election, and a couple of weeks later Labour were thrashed in the local elections, yet she still managed to burn through that poll lead with just a couple of weeks of stupidity.
