It's easy to know where presidential candidates John McCain and Barack Obama stand on ever-hot topics, like the war or abortion. But what about various areas of scientific interest? Science Debate 2008 has made it their focus to clarify each candidate's stance on issues like genetics research, energy and space. The full text is available at that link, but for those who enjoy abridged versions, the New York Times did a nice job of cutting the big block of text into bite-sized pieces.
The NYT points out that both candidates agree that global warming exists, though McCain would like to see carbon emissions drop by 60% while Obama aims for 80%. Similarly, both agree that genetics research is promising but frightening in its implications, assuring to fight workplace discrimination based upon one's genetic code and continue the genetic modification of crops.
The biggest difference I noted was McCain's interest in space. It's one of the few responses where McCain's opinion is lengthier and more policy specific than Obama's, assuring continued NASA funding and naming space exploration as a "top priority" while citing project goals like shortening space shuttle redesign turnaround. Obama feels it's more important to delegate the responsibility/policy, opting to reinstate a White House Space Council.
