As several political journalists and commentators are saying on Twitter, Democratic politicians are dropping like flies. Within the last few hours alone we’ve had a governor and senator announce retirement.

The governor? Colorado’s Bill Ritter, who was up for re-election this fall. Apparently he wasn’t looking forward to delivering a concession speech on election night.

WASHINGTON — Democratic sources tell The Associated Press that Colorado Gov. Bill Ritter won’t run for re-election this fall.

The first-term Democrat was elected in 2006 in a pivotal swing-voting state. He has been widely considered a rising star in the Democratic Party.

Two Democrats with knowledge of Ritter’s decision disclosed it on the condition of anonymity because they weren’t authorized to publicly discuss the governor’s political plans.

So long, Billy. You and Dorgan enjoy your retirement now, ya hear? Blanche Lincoln, Chris Dodd, and Harry Reid will be joining you next January.
