Let's not misstate the facts here.

It isn't Obama telling these people their vote doesn't mean anything. Long before the primary, the Democrat National Committee made a ruling that that those states had broken the rules and, as a consequence, their delegates would not be seated. Therefore, contrary to your insinuation, the people who voted were made aware before doing so that their votes wouldn't count. Obama had nothing to do with that.

Now, after the fact, the Clinton camp is advocating changing the rules.

Furthermore, you have also misstated Obama's position in terms of the superdelegates. Obama has not tried "to change the role of the superdelegates." To date, he has simply advocated that the delegates vote for him which is, of course, his right and consistent with the superdelegate process.

I will give you one point, however. You are correct that Clinton's effort to tear your party apart can only be good for the GOP.
