Obama, Who?

I have been only half listening to all the convention coverage and I have to say I'm more than a little confused. All the pundits are saying that Obama needs to introduce himself to the public so that the voters can know who he is and what he stands for. I rather thought that was what he has been doing for the last 18 months. Apparently I missed something. The pundits all believe that only those people that have been voting in the Democratic Primaries know who he is and the rest of just haven't been paying attention.
Another thing that I have missed is that the Convention in Denver is about the Clinton's. Again according to the pundits the Clinton's must convince Hillary's supports to move over to Obama. Also Bill must be seen to support Obama unconditionally or the Party may fracture. I thought it was the Democratic Party not the Clinton Party. Bill Clinton is just a former Democratic President, you know just like Jimmy Carter but again there must be something that I missed. Obama got this far without the help of Bill and Hillary Clinton I fail to see why he can't go the rest of the way without them. Isn't Obama running as the candidate of change and don't the Clinton's represent the politics of yesterday and the last century for that matter.
Obama if he is to win must continue doing what got him to this position. He needs keep talking about change. He needs to show that his ideas and policies will help make America safer and respected in the World. He needs to show how he is going to help improve the economy. He needs explain his energy independence plan. He needs to show how his diplomacy will work with Iran and the re-emerging Russia. He needs to talk about what he is going to do rather who he is.
