Senator Sanders may not receive the Presidential nomination, however that is only half the battle.The other half is to revolutionise Congress. Bernie should extend his influence to getting Congressmen of integrity elected.
The political powers of both parties have yet to acknowledge or recognise the fundamental ethic behind the popularity of both Sanders and Trump: the American people are simply tired of Politics as Usual. To not extend The Revolution into Congressional races would be to miss a rare opportunity to clean up Congres.
The reason we Sanders Revolutionaries could have a real effect on Congressional election outcomes is that most elections are decided by a few percentage points and a concerted vote by a relative few can decide the contest. The problem is which candidate to focus on.
On his web page Bernie could have his recommendations for each Congressional seat up for grabs this election season. Imagine a spreadsheet type page: One would click on one’s State then any of the Candidates. The spreadsheet columns would have Bernie's’ recommendation and the candidate's’ position on the critical issues etc.. Whatever variation on this theme is fine; the point being that it focuses Bernie’s revolution on Congress, which is actually more critical to effecting change than is the Presidency.
Whether the subject is the 1%, and their unfair share of the national wealth, inaction on Climate Change, True Election Reform or other critical issues we will not get action until Special Interest Influence is removed from Congress. Only the Voters can change the mentality of Congress. Congress writes the election laws and only our elected representatives can change them. Hence the primary criterion on Bernie’s spreadsheet would be: “does this candidate believe in True Election Reform”?.
