I just finished reading The Republican War on Science by Chris Mooney. Very very good work. Good, clear, logical arguments that both explain the current status of various scientific research areas (global warming, stem cell research, etc) and also show how various Republican politicians lie about alleged controversies in these areas. He places particular emphasis on the current White House of course but also connects anti-science thinking with conservative philosophy in general and Christian Conservative Republicanism in particular. A fair analysis as well; he also mentions examples of Democrats and environmental groups politicizing science but in doing so shows the difference between the groups in both quantity of times and magnitude of the dishonesty.
A very good read, even for someone who may not know the specifics of the issues.
