When we see reversion to the primary oral form, the truth can be revealed quickly in resonant fashion. Think of two examples from the 2008 campaign. Obama's "share the wealth" comment revealed a decided Marxist/Leninist bent, now proudly displayed. The possessors (i.e whoever is the target that day) should tithe, donate, invest, etc . . . to the disposed. The dictatorship of the Politically Correct decides how resources of the society are to be allotted, not the individual or the merits of his ability. Therefore, central control is best for all.
While John McCain had many more revealing unscripted moments, his snap decision to suspend his campaign revealed that his primary orality actually seemed to dictate his decisions. The stream of conscious oral formulation gave McCain an appeal, but showed a mind heavily influenced by intuition. In the chaotic environment of the fall of 2008, this characteristic reflected poorly on him and he subsequently began a drop in the polls from which he never recovered.
For Obama, talk is the goal in itself, until someone else caves or something else happens. This almost mimics a pick up artist at party. He works the room until a willing accomplice is found or prospects dry up and he goes to another party. Above all for Obama, if it's not working, keep talking. The Narrative (I predict this word will eventually be as loathsome as "mission statement") must be continually pushed to dominate the national discourse and to stiffen the spine of an increasingly wobbly Democratic Party, that perhaps is not sold on the idea of Obama running for re-election in 2012. Unfortunately, dullness has set in. President Obama has become one long boring ineffectual scold. In the age of Twitter, this President is digging his own political grave, unless Republicans decide to help dig him out. They would be better served to let him keep talking.
