Edwards's Working Class Pull?
Not so fast says 538:
It seems to be taken for granted that John Edwards had some stranglehold on the working class white vote. But this was not really the case. The working class vote was not a particular strength of John Edwards in either relative or absolute terms.
Edwards’ working class appeal is more limited than it appears. Appearances, however, are important. While the endorsement may not help Obama with actual working class voters, it will help in the realm of media perceptions, which is the only game that matters at this point (sadly). The chattering classes perceive Edwards as having significant working class appeal. Thus, we’ll hear over and over this week about how Edwards West Virginia aside strengthens Obama’s working class street cred. This chatter, in turn, will help strengthen the resolve of superdelegates and other party establishment figures who are beginning to coalesce around Obama.
