Something like:
Up-or-Down Vote party Free Choice party Issues-First party Free Speech party
Then just message over and over again "Let's agree to disagree", explaining that we are held hostage by two choices when there are so many more positions to take.
This party doesn't take a stance on particular issues, but it takes a stand on how issues are discussed - it raises money for candidates that agree to recognize the validity of facts, of logical arguments, of admitting when you're wrong about something, and respecting the variety of opinions and beliefs that flourish in America and that recognize the validity of evidence and reason.
