Bernie Sanders could win my undying affection on Tuesday night if he does one thing:

5. Advocating policies that over promise, under deliver and never get passed is not a progressive value

It is political masturbation that gratifies your pleasure center but doesn't achieve an actual result.

Passing landmark legislation like the ACA, building public trust and expanding its coverage and revising its practice in the actual body politic is how all of our most progressive government programs from Social Security to Medicare have evolved.

It took Canada 20 years to move from provincial hospital coverage to universal coverage. We can accomplish that in 10 years by building on the ACA with a Democratic President and Congress.

And THE most important skill set of any progressive leader is the ability to forge coalitions with people outside your ardent group of supporters.

No one has failed more than Sanders (some may have tied) to establish broad coalitions as a Senator or a candidate.

The label "progressive" is not achieved by self proclamation but by forging winning coalitions and getting legislation passed. That us the only metric that counts and the only value that is meaningful and why President Obama is the most progressive leader over the last 50 years.
