He isn't marginalizing them.  Obama's said he'd do whatever the DNC and the state decided.  The DNC said hold a revote and we'll seat your delegates.  Florida can't seem to get their stuff together and do it.  

That's not Obama's fault, and he isn't marginalizing them.  

Even so, I think at the end of the day they'll end up seated somehow.  

Now as far as winning Florida, if you're looking at current polling, it doesn't look like either of our candidates have a chance of winning that state.  As far as Obama's electoral map, it seems to consist of winning a number of purplish swing states that Hillary has written off, just like our last few losing presidential candidates.  

Your comment really does not make sense.  Your claim is that the best possible outcome to an Obama nomination is a loss to McCain.  Certainly this could happen, but you are quite literally saying that it's totally impossible for Obama to win the GE.  Which is simply unrealistic.  Futures markets and polling suggest that even from a highly pessimistic POV it's easily within the realm of possibility.  Sticking your fingers in your ears and saying "IT CAN'T HAPPEN" doesn't really change anything.  I'm not saying there aren't obstacles, but Clinton's only path to nom. includes many more and higher hurdles.  One could very legitimately state that a Hillary superdelegate coup would be equally pyrrhic, if not far more, as it could damage the party for many years to come and destroy the current massive influx of youth voters who will be the next generation of Dems.
