Brian Beutler has a great piece up on “The Year in Oversight,” and notes a point that doesn’t get emphasized nearly enough:

There certainly have been gaffes, softballs, and missed opportunities. And the most obvious are found in the Senate Committee on Homeland Security — the Senate’s version of Rep. Henry Waxman’s Oversight Committee in the House. Unlike Waxman’s enthusiastic probing, the Senate chair conducted zero proactive investigations into Bush administration malfeasance. It’s chairman? Connecticut’s Joseph Lieberman.

Senate Dems need to deliver a message to Lieberman: Use it or lose it.
