I remember reading the book "The Powers That Be" by David Halberstam where he talks about how first the radio and later the Television made the US president much more powerful than the Congress. American democracy was much more local and decentralized before radio, and no President could get away by ruling with executive orders. In the age of social media, everyone just self bins into a few national buckets and votes accordingly, even in local elections.
