Last night was the final opportunity for six Democratic hopefuls to make their presidential pitches before the first primary in Iowa on 3 February. While most of the mainstream media focus was on a spat in the progressive wing of the party, a more interesting battle line was drawn elsewhere on the debate stage.

That might be an easy call to make for someone who’s net worth is in excess of $1.5 billion, but it does point to one of this century’s most difficult political questions: if being green starts making life harder for the working class, which do you prioritise?

Today’s announcement of a government rescue package for the British regional airline FlyBe is another example of the same tension.

The Independent has already come out against the rescue — showing how the new Left is already making a difficult choice.
