Mikulski to retire?

Lots and lots of retirements....via Instapundit via Vail Spot:

I've just heard from an impeccable source that Barbara Mikulski, the Democratic Senator who is up for reelection this November, will choose to retire. Mrs. Mikulski is expected to make her formal announcement in the next few days.Mrs. Mikulski seriously fractured her right ankle last fall just prior to Edward M. Kennedy's death. Due to the severity of the fracture, she had to have open reduction surgery, that included the insertion of pins, as well as the use of special surgical boots, during recovery. She had tried to arrive in time for Mr. Kennedy's funeral but was turned away.
