Since it looks like Hillary will be unable to win the most pledged delegates, the ones the voters actually select, she is looking for other ways to secure the nomination. The only way possible will be by convincing the superdelegates to override the will of the people. One of Hillary's arguments is that she is winning the big states. I find this argument weak in that what happens in the Primary doesn't necessarily mean it will happen in the General Election. Trying to win your party's nomination and trying to get elected President are two completely different things. Besides, even if Hillary wins the big states like New York, Pennsylvania, New Jersey, and California, it doesn't mean diddlysquat. Both Al Gore and  John Kerry won those states, but neither was elected President. Al Gore even won the popular vote, another case Hillary is hoping to make. Winning the big states are nice, but winning enough states to get the required number of delegates is more important.

What Hillary seems to miss is that Barack Obama has developed a strategy to win. If he is able to develop a strategy to win the nomination, I have to believe Barack's campaign can develop a plan to win the Presidency. Hillary's campaign seems to have developed a losing strategy for the Primary, which makes it hard to expect that  she could develop a winning strategy for the General Election. Like Hillary's assumption that she was the inevitable candidate to win the Primary, she probably would assume the same for the General. Hillary probably would even win some big states, but not enough delegates to win the Presidency.
