Both Hillary Clinton and Barack Obama hold similar views on most topics. I can identify only two significant differences. Barack Obama would be more willing to conduct direct negotiations with leaders of countries that have serious disagreements with the U.S. and he would raise the cap on social security taxes. Hillary Clinton would limit negotiations with other countries at odds with us and would not be willing to raise social security taxes.
So why have these debates? The Democrats are now down to choosing their nominee from two strong candidates. That means the voters will have to dig into their views and beliefs. Furthermore, voters will have to understand the thought processes of the candidates. That leads to appraising their previous life both public and private. Democrats can learn more about both candidates by carefully listening to what they say and have said, who they have associated with, and all manner of other things that most of us would consider personal (like religious belief, social behavior, etc.).
Hillary Clinton’s story about her landing in war torn Bosnia and Barack Obama’s membership in a church that spews hateful messages do count in the decision making process. Super delegates do have a purpose. They have the power to override the will of the people and they should exercise that power if they deem it to be appropriate.
