According to Politico, the race is over for super delegates. Clinton has lost, Obama has won. That would explain the shift in the Clinton campaign’s rhetoric over the past month or so from emphasizing the role of the super delegates to pushing hard on the popular vote, even though that’s not a determining factor in choosing the candidate, and never has been to my knowledge. I certainly haven’t found it come up in my wide reading about FDR and TR. It’s always the delegate count that matters.
Why aren’t people coming out in public? Timing and caution. Insiders also say that lobbying for super delegates has slowed down, which indicates that most decisions have been made. That would help explain the continued drumbeat from Clintonistas about the Michigan and Florida rule-violating primaries; but even then, the talk is always about popular vote more than delegates.
