"That’s the choice you face this November -- between dividing ourselves up, looking for scapegoats, ignoring the evidence -- or realizing that we are all stronger together. If we turn against each other -- whether it's divisions of race or religion -- we're not going to build on the progress we started. If we get cynical and just vote our fears -- or we don’t vote at all -- we won’t build on the progress we’ve started. America has been a story of progress, but has not gone in a straight line. There have been times where we've gone forward, there have been times where we've gone backwards. And what’s made the difference each and every time is citizens voting, and caring, and committing to our better selves. Coming together around our common values, and our faith in hard work and our faith in each other, and the belief in opportunity for everybody, and assuming the best in each other, and not the worst."-- President Barack Obama, June 25, 2016.
Comment: Obama is calling for setting a higher standard of debate, but at the same time he's demonizing his opponents as not caring about evidence. As a result, his remarks imply that it's mostly his opponents who resort to unfair rhetoric. Also, Obama is using "uniting, not dividing" rhetoric – though, how do you unify with people you accuse of ignoring evidence? – as well as "appealing to fear" rhetoric.
