There seems to be an assumption that politicians are divided, but Americans wish to be more united. The problem is: we are the divisions. There is no "us" (citizens) and "them" (national politicians). The pols reflect our divisions.

This is not to say that Obama's gamble isn't worth taking, nor that what he is doing isn't noble. Obama is an exceptional man for all of the reasons you have articulated on your blog. But I am not convinced that Americans want to be brought together. They may not want things to be as divided as they are now, but we still are divided on many key issues. And we're divided on what we should care about: economics vs values, for instance.

Remember: It was just 3 short years ago that 61 million people voted for GWB --- well after it was evident that his presidency was a disaster.

The fact is, Hillary vs Rudy may be exactly what the electorate wants.

It seems to be what Bush wants.
