I wasn't aware Jezza was a member of the Populist Right?
That method of thinking seems to indicate that Sanders would have won if he'd run against Trump. A fallacy, he wouldn't.....these voters would have just seen him as another out of touch liberal and it doesn't matter how long he'd spent as a senator railing against wall street and the plutocrats (for what it's worth i actually like Bernie).
Although i will do something uncharacteristic and say something nice about Corbyn, i think he would be a much better British Prime Minister than Trump will be an American president (that's more reflective of my low opinion of the Donald of course but everything is always relative to something else).
