The Pol State blog where I blogged politics before starting Wash Park Prophet, ceased operations on May 24, 2008 when Temple Stark, the lead editor there, shut it down.
Originally designed as a bipartisan 50 state political blog with corrospondents in each state, it fell victim first to partisan infighting (which was why I left), to technical difficulties, and then to the power of RSS based blog aggregators to appropriate more lively state political blogs. It was sponsored by DailyKos financially, but not affiliated with it in editorial policies or politics.
It had covered almost nothing about Colorado politics that did not touch on the Presidential race for a long time when it ceased operations.
Other Pol State alums from the Colorado political blogosphere include my predecessor Colorado Luis, who sometimes writes at Square State after discontinuing his highly insightful personal blog, and my conservative Pol State colleague who continues to be part of the Mile High Delphi team.
