To quote President Obama:
"They say, hey, I'm not a scientist, which really translates into, I accept that manmade climate change is real, but if I say so out loud, I will be run out of town by a bunch of fringe elements that think climate science is a liberal plot so I'm going to just pretend like, I don't know, I can't read." — June 25, League of Conservation Voters dinner
"I mean, I'm not a scientist either, but I've got this guy, John Holdren, he's a scientist. I've got a bunch of scientists at NASA and I've got a bunch of scientists at EPA."
"I'm not a doctor either, but if a bunch of doctors tell me that tobacco can cause lung cancer then I'll say, 'OK!' It's not that hard."
"I'm not a scientist, but I read the science."
