Daniel Hannan is in trouble. The young Tory European MP, who became a YouTube sensation earlier this year for his denunciation of British Prime Minister Gordon Brown as the "devalued prime minister of a devalued government," has made what can in politics be a serious error: he has challenged orthodoxy in a way that is both substantive and interesting. Boring substantive challenges can be seen off, and soaring rhetoric that says nothing is the stuff of politics, but having a point and knowing how to make it will always raise bellows from the defenders of the gored sacred cow.
