We won't get someone as good as Corbyn in America sadly.
It mystifies me how anyone even someone left wing can think Jeremy Corbyn is a good leader. His leadership is an utter shambles with mind-bogglingly incompetent statements and political stunts turning him into a national laughing stock, lack of message discipline, no economic plan (they were so clueless on this front that even left wing academics like Piketty gave up on them), infighting, anti-Semitism scandals and questions over links to extremists and terrorist groups. This allows Theresa May and the Government to look frankly amazing in comparison. With a non useless Labour party they'd be up the creek without a paddle. Even a lot on the left of the Labour party are starting to see what a catastrophe Corbyn is, a lot of them want to ditch him but are afraid that the parliamentary Labour Party will use the leadership rules to keep a less crazy left wing alternative off the ballot.
I think you need to brush up on British politics because if your solution to the Democratic Party's woes is drafting a privileged, far leftist who's never done a days proper work in his life and who's loyalty to the country can be called into question then god help the Democratic party and be prepared for a Trump landslide. If you don't believe me check out opinion polling where the Tories are up on Labour by huge margins while in government (sitting governments usually poll terriblly mid term and when they don't it strongly indicates they are on course for a landslide re-election) and Corbyn's dire personal approval ratings (the worst for a party leader since polling began).
