He's done. The Star Tribune (www.startribune.com) has the information. Lots of rumors going around right now, but only one declared DFLer in the race, a young (only 29) woman named Mattson, whose father and grandfather were political figures in Minnesota. Other potential candidates are Mike Freeman (Amy Klobuchar's predecessor as Hennepin County DA and the son of Orville Freeman) and Bill Luther, the former congressman. This race is getting a heck of a lot more interesting.
We'll do a little more schadenfreude on Mr. Entenza when I have time. Put it this way - even if you are a DFLer, this guy was the poster child for everything that's wrong about modern Democrats. The contrast between him and the other heavyweights on the ticket (Hatch, Klobuchar, etc.) could not have been more stark. Good riddance.
