Umm ...
Seriously, the latest issue of Nature has a special section on the US presidential election, including another Q&A with the candidates:
Barack Obama accepted Nature's invitation to answer 18 science-related questions in writing; John McCain's campaign declined. Obama's answers to many of the questions are printed here; answers to additional questions (on topics including biosecurity, the nuclear weapons laboratories and US participation in international projects) can be found at
www.nature.com/uselection. Wherever possible, Nature has noted what McCain has said at other times on these topics.
