Its not over yet, not by a long way.
People still think that Hillary will win Texas and in the end no one candidate will have the delegates to make it to an outright win.
At the last count, both candidates now have to win by a 10 %point margin in all states to win a nomination. Which is highly unlikely(atleast impossible for Clinton) so that will mean a battle for the super delegates and they will vote based on electability and past records where Clinton will win.

Already you will notice the Obama camp is saying that disregarding the people's verdict would be a disgrace in a sure sign to put some pressure on the super delegates.
