Ed Milliband looks and sounds strange.
There is no getting away from that fact.
He might have a mind as sharp as a needle, and he might be nice to his family, but as a leader and an international statesman he simply hasn't got the elements required.
One is that you don't look like a human constructed from an alien species who used old Woody Allen films through hazy projectors to create their model.
Two is that when you talk, you don't sound like you are trying to swallow a golf ball while being simultaniously waterboarded by someone who has your testcles in a vice and is drumming their fingers on the tightening handle.
Solve those two, and Ed coiuld be electable, but as it is ....
The difficulty Labour have is that they got all giddy and chose him over his brother, and now they are stuck with him because to ditch him any time in the next twelve months would make them look like mealy-mouthed backj-stabbers. Which they are, but the don't want to make it obvious to the voting public.
