There needs to be an arm going from the Dems to the UL at the UL's inception. Several of our founding members (granted, not the most active ones now - Migrendel, MikeZ...) were never Progressives.
And to Jesus I have only one reply:
I was the forty-first person to register in Atlas politics, the second to register as something other than Dem or Rep, and I have NEVER been affiliated with the Dems or the Reps.
The Progressive Party, which was the first third party, died out. The Jesus Christ Party was fourth, and due to the extinction of the Progressive Party is now the 3rd longest living party.
