Will Brownsberger has entered the race to succeed Ed Markey in Massachusetts. Will and I don’t always see eye-to-eye on drug policy and crime control, but his election would roughly double the total current stock of Congressional expertise on those issues. He’s also serious, thoughtful, practical-minded, and frank.

And no, I can’t figure out why someone like that would want to serve in the current House of Representatives. But if he’s willing to take a bullet in a good cause, the rest of us can at least help out.
