After President Obama took office, his campaign book 'The Audacity of Hope' receded into his past fast. Its sweet, naive, bipartisan 'let's reason together' passages fell away, too.

The challenge with Donald Trump is that he'll deny things he said the day before or even in the same interview. And then sometimes when you try and talk about a fact that he misstated or something that he said out loud that he now disagrees with himself on, it's very frustrating.

Campaigns maybe encourage us to pay attention to attributes that maybe aren't that important in the presidency.
