Why are the liberal media and politicians in the West fixated on 'that film'?

'...the film has even less to do with anything than did the Danish cartoons or the schoolteacher’s teddy bear or any of the other innumerable grievances of Islam. The 400-strong assault force in Benghazi showed up with RPGs and mortars: That’s not a spontaneous movie protest; that’s an act of war, and better planned and executed than the dying superpower’s response to it.'

That was Mark Steyn in The National Review making more sense than the BBC, CNN, MSNBC or any of the other western news media who are way more interested in ensuring Barack Obama is re-elected than that the truth emerges about radical Islam's continuing war on 'the west.'
