A poster? lol no.
Miles did get successful, though. But to be fair, he was one of the best posters here.
Who?
J. Miles Coleman. He's a member of DDHQ and posts sick maps on his Twitter. He used to post those maps here.
Lunar is super successful too. And Phil works for Toomey, so who knows. Maybe one day he'll run for something.
Does Phil count since he specifically quit Atlas once he started working for Toomey.
I will also note that it's not that crazy and alternative timeline where muon got elected to Randy Hultinger's seat sometime when it came open. Though it might have been difficult for him to win a primary.
