The Deputy PM's pragmatic case for the EU gave him the edge over the tetchy UKIP leader.
The average British voter is not convinced by the case for the EU, nor persuaded that we would be better off out.
Clegg's party has lost more than 500,000 voters to Farage since 2010.
Alien holograms from the EU are coming to get your money, apparently.
There are far more people who don’t vote Ukip than do, including many who despise pub-bore nationalism.
Guaranteeing an in/out vote would have shifted the debate back onto Tory territory and could have wrecked a future Miliband premiership.
Farage gets to enter the political establishment, while Clegg has a chance to reconnect with those voters who warmed to him in 2010.
Miliband's northern fortresses are safe but Farage's party could prevent Labour winning southern and eastern marginals off the Tories in 2015.
The decision means the party will now be entitled to equal levels of TV coverage as the other main parties.
It will become harder for the PM to insist he can succeed when the europhile and the europhobe both declare he will fail.
