Given that Donald J. Trump is almost certainly our next president, I believe it's more important than ever for all moderates, centrists, reasonable liberals and sensible conservatives to join together in a loyal opposition. Because only by speaking with a loud and unified voice can we hope to blunt the damage this man--and I use the term loosely--could cause to our country and our world. To that end, I propose we start a discussion on the best way to build that opposition. I think at minimum we need a better communications platform to get our word out. We also need to work out some means for people to debate issues in a controlled fashion (like local debating societies or citizen assemblies) so that the people can find and build on common ground. I'm not sure blog posts are adequate for that purpose. This isn't about building a third party movement anymore. It's about the future of this Republic and its people. Trump cannot be allowed to govern unchallenged. With Congress in Republican hands, only an organized, active, and extremely vocal citizenry can provide that challenge.
