He's right. When an impeachment is going on, everything else DOES grind to a halt. But you know when ELSE everything grinds to a halt? When the president and half of congress opposes everything that you're trying to get done. Not impeaching, so that you can focus on "raising the minimum wage and extending unemployment compensation, as well as ameliorating the mortgage crisis and gas prices", doesn't get us anywhere that impeachment proceedings wouldn't. "Diverting out energy" won't stop us from fixing the problems. And maybe, just maybe, there's a tiny little sliver of hope that bad people will be stopped from doing bad things.
I think perhaps I might just copy and paste this into a reply.
