Do you think we need more scientist politicians?

Yes, we do. Most scientists, myself included, wouldn't be interested in entering politics, but fortunately there are a few that are. And we need more of them. Our current government seems oblivious to the fact that there actually are facts out there to work with, and you don't get to contradict them by being really, really loud or really 'believing' you're right. Climate change is happening, whether you like it or not. Abstinence doesn't work, no matter how much money you throw at it. Alternative medicine wouldn't be considered alternative if it actually worked. Fortunately, the FDA is starting to catch on to that. But we need more people training in logical and critical thinking in charge, and fewer people who think that some god is telling them what to do.
