That's what I was thinking – "it's too complex and being careful will not work here" seems more like the implication.
I don't know though; the obstructionism is really entrenched and it would be almost impossible for the Democrats to build any bridges. In many ways, Obama was about as good a chance as is likely for a while – a good speaker, moderate, positive and willing to cooperate. The fact that the knot has only got tighter is not a good sign.
The one thing I can think of is that some people identify with certain groups for specific reasons, often based on perceived shared values. I don't want to wish for a bad presidency, but maybe that would help people to leave in larger numbers.
