Yup. Strange thing is, he didn't have to try too hard. In fact he and his shadow chancellor Diane Abbott didn't seem to try at all (tho at least Jezza did turn up)... the plain arrogance of the PM fought their corner for them.
The Labour campaign was much more positive, much more pro Labour. The Tories campaign was almost completely negative and anti Corbyn. They used grubby tabloid tactics. If they mess this up tonight then I believe that's a big reason why.
