The voting among the 447 savants is not a test of Ellison nor Perez. It is a test of 447 individuals, some, likely, full of themselves.
NOBODY has asked if there is a popular opinion favorite. The DNC is full of political science graduates and they know little but polling.
Why have they, and the outside "specialists" in polling not looked at their home state registered Democratic VOTERS, and sought information?
BECAUSE THEY DON'T CARE A RAT'S ASS WHAT PEOPLE THINK AND THAT AUGERS POORLY FOR THE INNER PARTY'S RELEVANCE, REGARDLESS OF WHICH FACTION PREVAILS, WHICH OUTCOME RESULTS. IT IS AGAINST THIS BLOCK OF STONE COLD GRANITE SELF-CENTEREDNESS THAT ELLISON IS TRYING TO EDUCATE. THEY SEE IT AS A HORSE TRADING GAME, OR A WE HOLD THE FUTURE GAME; BUT AS TO WHETHER THERE IS A PUBLIC CONSENSUS THEY SIMPLY DO NOT SUFFICIENTLY CARE TO ASK.
