The fundamental problem is that there isn't a credible 'progressive' leader to lead the democrats...and galvanise the pure progressives grass roots masses.
Bennie Sanders is too old and weak.....He talks the talk but does not walk the walk.
After prostrating to Hitlery last summer he brought his third 'progressive' home for $600,000...and said thank you very much Israel/AIPAC/Wall Street.
Susan Sarandon is also too old as is Sally Fields.......The Democrats need a 40 something WASP male with strong integrity and character (No Jew links)...and someone who is not a corporatist front.
I notice the number of Jews, and ethnics in the DNC.
Then conduct a coup in the DNC.
