George LakoffBarack Obama understands what Ronald Reagan learned, which is that people vote not on the basis of issues and policy details, but on the basis of something deeper, namely, what are your values? Are you authentic? Do you say what you believe? Do you communicate with us? And do we identify with you? You don't know what particular issues are going to come up in the future, so you have to depend on someone's values, and whether they are telling you the truth, and whether you can trust them in office. Obama's been running a campaign on that basis.

George LakoffLiberals have a set of folk theories that are fallacious. One of them comes from the Enlightenment, and the assumption is that you are supposed to be logical.
