Politico’s Stephanie Murray joined Boston Public Radio on Monday, where she talked about the latest in Mass. politics, from the Senate race between Sen. Ed Markey and Rep. Joe Kennedy, to controversy that’s shaking up Holyoke Mayor Alex Morse’s campaign for Congress.

Less than a month from the Sept. 1 primary, Murray said of the Senate race, “it’s expensive, it’s ugly, and the stakes are very high.”
