Democratic pols, consultants, activists, voters - please hammer this bit of information into your brains.
Republicans understand what the philosopher David Hume recognized three centuries ago: that reason is a slave to emotion, not the other way around. With the exception of the Clinton era, Democratic strategists for the last three decades have instead clung tenaciously to the dispassionate view of the mind and to the campaign strategy that logically follows from it, namely one that focuses on facts, figures, policy statements, costs, and benefits, and appeals to intellect and expertise.
In 2002, 2004, and 2006 Democrats have made a habit of throwing out a lot of dates, numbers, etc. and expecting the public to actually put facts together. You got lucky in 2006, and it's just not a workable strategy. Saying "SEEE????!!!!" is not a substitute for doing the work of getting your message as solid and digestible as possible while aiming for the voter's gut and not his or her brain.
