I was somewhat impressed by Josh Kraft’s launch of his mayoral campaign yesterday. He didn’t look and sound like a newcomer to politics. No rookie stumbles and gaffes, etc. Instead, he sounded confident and prepared as he spoke to the cameras with an obligatory diverse group of supporters in the background. … OK, so that’s a style-over-substance view. But Contrarian Boston’s Scott Van Vooris was also impressed by his first-day focus on housing costs. “He’s sure picked a great issue to run on,” he writes. … The Globe’s Adrian Walker questions whether going all negative on Mayor Wu is enough to win in the fall. … And Wu is already hitting back at Kraft’s newfound Boston residency, as the Herald reports. …

My money’s still on Wu, an incumbent with a proven track record of winning citywide elections. She’s vulnerable. But not that vulnerable.
