Clegg v Farage debate poll
There is a YouGov/Sun instant reaction poll of people who watched the debate (weighting to be a representative sample in terms of party support and attitudes to EU membership). Result was a pretty comfortable win for Farage: 57% think Farage did better, 36% think Clegg did better.
UPDATE: A long day, but a few thoughts about the Nick v Nigel debate. First up, remember that the vast majority of people didn't watch it - to get 1000 people for our poll of people who were watching it we had to ask tens of thousands of people. Of course, that will be multiplied by people who didn't watch the debate seeing the subsequent media reporting... but remember, most people didn't see it.
Secondly, remember that this was not a zero game and in many ways it is not impossible for Nigel Farage and Nick Clegg to both come away with positives. While there is some crossover between UKIP and Lib Dem voters (the Lib Dems used to be the natural recipient of the "plague on both your houses vote" that now more naturally rests with UKIP), this wasn't really a debate between two politicians seeking to win the favour of the same groups of voters. They had different reasons to be there.
Nigel Farage was there seeking to look like a serious figure leading a party that deserves to be taken seriously and be ranked along the other large parties. He was staking a claim for UKIP's place at the top table. Clegg meanwhile was tying to put forward a positive reason to vote Lib Dem - Euro-enthusiasm is very much a minority pursuit in the UK, but there are a minority who are positive and enthusiastic about Europe and for a Lib Dem party hovering around the 10% mark in the polls it's worth trying to appeal to them.
Meanwhile, tonight's YouGov poll for the Sun had topline figures of CON 35%, LAB 37%, LD 9%, UKIP 11%
