Last night a thought came to my mind on a possible reason why the circumcision debate, although strong among today's new parents in America, is not getting as much attention as issues such as abortion or health care reform. The latter two issues are largely split along the liberal vs. conservative line, while both the strongest supporters and opponents of circumcision tend to be liberals. Jews and Muslims (two groups with their long tradition of circ) tend to lean left, as do the "free-thinking" anti-circ crowd (e.g. a dominant group in San Francisco, where a circ ban will be on the ballot in a few months). American conservatives, on the other hand, are as a whole neutral on the circ issue (with neither a religious or other tradition nor a strong incentive to disapprove of it). This is of course a generalization; individual results may vary (thought I'd put in that disclaimer).
This also explains how the circumcision rate in the two "blue state" regions vary a lot (the West's low circ rate vs. the high rate farther north and east), with the conservative South falling in between.
