Was it a good idea to split the vote for the Democrats?

The Democrat race for presidential nominee will now depend on which way the superdelegates go, which isn�t really very democratic. This would have never happened if the Democrats used a winner-take-all format like the Republicans (whichever candidate who got the most votes in a state would win all of that state�s delegates). Do you think the Democrats should go back to a winner-take-all format for the next presidential race?
