Well, of course.
Firstly - as the article points out - the audience was picked by ICM (not the BBC) to represent the make-up of the parties taking part. The audience was therefore obviously going to be mostly left-leaning because most of the parties were.
Secondly, it has to be remembered that the leader debates have been set up the way they have been not because the BBC and the other TV companies wanted them like that, but because that's how David Cameron wanted them.
The BBC was basically given Hobson's choice: Cameron would only agree to any debates if they were entirely on his terms.
Cameron insisted on the initial 7 leader debate instead of the originally planned "big 4" (him, Miliband, Clegg and Farage) to reduce the image of a "divided right" (i.e. him being attacked by Farage) and replacing it with a "divided left" left scenario as Miliband would get attacked by the other party leaders who were brought in. The defining image of that debate was Sturgeon laying into Miliband as Cameron looked on from the sidelines, grinning like a Cheshire cat as he watched Sturgeon do his work for him.
Last night's debate was planned in a similar way - only the Tories prevented the Lib Dems from taking part so there was no chance of any Government representative being held to account this time. Again it was Miliband who was targeted (defining image: the "group hug" by the three female leaders), with Sturgeon once again conveniently playing along to current Tory campaign strategy by insisting on a Labour/SNP deal and all the time Farage (the Tories biggest worry) looked isolated and frustrated.
Job done, Cameron...
