the moment where this presidency turned a corner?

"... when any government measure, no matter how carefully crafted or beneficial, is subject to scorn; when any efforts to help people in need are attacked as un-American; when facts and reason are thrown overboard and only timidity passes for wisdom, and we can no longer even engage in a civil conversation with each other over the things that truly matter ... at that point we don’t merely lose our capacity to solve big challenges. We lose something essential about ourselves." -- POTUS No. 44
