In reply to Offwidth:
I heard a bloke on the radio last night talking about something related. This bloke had worked for Tony Blair on election campaigns IIRC.
He said that about 30% of the electorate are instinctively hostile to authority and will vote against it given the chance. It's not ideological it's just the way they are. Up until not that long ago these people were ignored and election campaigns were arguments on policy. Now though these people are brought into campaigns by appealing to their prejudices. That is where populism comes from and you can see in the article that it was precisely those people that Dominic was aiming his message at. Nihilists I suppose.
