Yes, without the £3 vote he got 51/52% (so not as good as Tony Blair after all), so he would have won anyway in the first round, though it could have turned out slightly different perhaps if it had been closer.
Also, despite his wave of so called popular support, only 105,000 people voted (of which he got 84%) which is hardly going to swing an election. I like his charisma, I like some of his principles, but there are a lot of middle class people who will be afraid of him ultimately.
