Isn't this faction of the Democratic Party totally irrelevant ? (no offense leftists)
Considering this is the faction that largely comprises the activist groups and Democratic county parties throughout the country, no. Everybody can laugh about how small of a faction they are in numbers, but in terms of dollars and volunteer hours, they very well may be a majority. Sure, crapping on them isn't going to cost a candidate a primary victory (unless it's 2008-close all over again, LOL), but it very well may wind up costing them a general election victory when you factor in the loss of enthusiasm and motivation for these people to organize, volunteer and otherwise go above and beyond in getting their preferred candidates elected.
