I'd challenge anyone to present a link to a substantial article or video where a noteworthy democratic politician actually addresses in detail some of the very big problems in the current system, rather than just speak in feel-good generalities that if implemented could easily allow corporations to continue charging at current levels for delivery even under a single-payer system.

Until then, I will continue to believe democrats and republicans serve the same master and only differ in language to provide an illusion of choice.
