"No words can adequately express the sadness we feel at this moment as we contemplate the loss of yet another law enforcement officer in the line of duty," Papenfuse said. "I extend my sincerest condolences to the family of the slain U.S. marshal, to his colleagues and to all law enforcement officers who risk their lives each day to protect and to serve our city and our nation."
But it's not at all clear that such campaigning persuades Trump voters to vote for someone other than Trump. Saccone may borrow the Trump slogan -- "This campaign is about something bigger than any of us ... making America great again!" he roared at a Saturday rally -- but he hasn't shown signs of tapping into the 2016 enthusiasm on the right. That momentum, it seems, has swung to the left -- and that frees up candidates like Lamb to aim for the middle.
