Democrats have totally lost the centre ground in American politics
There is a real possibility that the Democratic Party of the United States, has surrendered any hope of attaining the centre-ground for at least generation.
Throughout most of the 20th century, both major US parties attempted to appeal to different interpretations of the centre.
The Republicans were broadly centre right but shunned the far-rightism of organisations like the John Birch Society.
Likewise, the Democrats were centre-left whilst rejecting organisations of the far left; groups like Students for a Democratic Society.
