Time served

The Recess Supervisor at Playground Politics looks at State Rep. Sheldon Wasserman's (D) term limit promise and does a little math:

So in other words, Wasserman vows to end his career in public service by 2020, at the age of 59. By then, his WRS age reduction factor will be .981. Not sticking around for that extra 1.9% proves that he is the real fiscal conservative.

Also pretty easy to make that kind of promise if there's a good chance you won't win.
