Yes, that’s true. The poll averages themselves haven’t moved much either though. And the reliance on the fundamentals forecast has me nervous, but they definitely do it for a reason. When they developed the models and looked at poll history the pattern they found was the fundamentals had a big influence on what the polls would look like closer to the election and the eventual result. Polls closer to the election are more predictive than the fundamentals. Polls farther away from the election less so. There’s at least some reason to think things have changed enough maybe the fundamentals aren’t as fundamental for this race, but I guess we won’t know until afterward.
People keep seeming to forget about the super delegate reform Bernie fought for. They are still there now, 15% of all the delegates (a lot of the super delegates being democratic elected officials like members of congress since that automatically gives the status). But they can’t vote in the first ballot any longer. They could only vote in a contested election in subsequent ballots, after all the other pledged delegates are unbound as well.

Even before those reforms, they never really made a difference in any convention, except possibly 1984 when they helped push Mondale from a plurality to a majority by voting for him on the first ballot.
I’m not personally in favor of them at all, but it’s not nearly as bad as it’s made out to be sometimes. If we go to an open convention though, unless there’s a majority choice on the first ballot, they may play a role on subsequent ballots.
