The phrase “mealy-mouthed politician” often seems redundant, so closely do we associate political figures with an aversion to direct answers that cut through the usual fog.

That does not describe Seth Moulton, the second-term Democratic congressman from Salem. Moulton answers questions with a degree of candor that is refreshing and sometimes jarring.

When CommonWealth sat down with him for this Conversation interview in November 2014, just after his election, Moulton said he was now wearing the politician badge reluctantly. When Bruce Mohl and I talked to him for this week’s Codcast, he still seemed to be in full candor mode.

The spring issue of CommonWealth magazine is out, and you can not only read it all online here, you can listen to us chew over some of the stories in this week’s Codcast.

Patrick Sullivan, executive director of the Seaport TMA, estimates 4,000 people on a typical weekday come into North Station and then take shuttles to the congested Seaport District. He said his organization hopes to eliminate a lot of that vehicle traffic by launching a water shuttle between Lovejoy Wharf and the South Boston waterfront this summer. Test runs showed the trip would take about 13 minutes.

Sullivan, participating in the Codcast with James Aloisi and Marc Ebuna of TransitMatters, said Silver Line service from South Station to the Seaport District is at capacity most weekday mornings, but there are no plans to expand the 32-bus fleet. The three discussed ways to boost capacity by creating dedicated lanes or adjusting traffic signals to speed up the buses.

Massachusetts is about to submit to the US Department of Education its plan for monitoring and holding schools accountable under the new Every Student Succeeds Act, the law passed in late 2015 that replaced the No Child Left Behind law.

The new law, which, like the No Child statute, is really a reauthorization of landmark 1965 legislation creating a bigger federal role in overseeing and funding education, gives states more leeway in how they hold schools and districts accountable for improving student outcomes.

MassINC research director Ben Forman and Linda Noonan, executive director of the Massachusetts Alliance for Education, say the state plan mainly holds pat.

State Treasurer Deborah Goldberg says when she talks to counterparts around the country, there is one aspect of her job that stops them in their tracks: Her office’s regulation of the state’s liquor industry.

Goldberg now has another mood-altering substance to oversee with the passage of the ballot initiative to legalize recreational marijuana. Under the wording of the ballot question, the treasurer’s office will appoint a three-member Cannabis Control Commission that will form rules and regulations and report to the treasurer. Goldberg joined The Codcast to talk about her thoughts on ramping up oversight, which she said she’s been planning for since learning about the ballot question 15 months ago.

Beth Osborne, a senior advisor for Washington-based Transportation for America, was in town recently to discuss transportation needs with state officials and policy advocates. Osborne, a former undersecretary in the Department of Transportation and a longtime congressional aide to several lawmakers, said Trump’s “skinny budget” isn’t going to give a lot of answers for transportation, at least in the immediate future.

Osborne joined Transit Matters board members Josh Fairchild and James Aloisi for this week’s edition of The Codcast, and they talked about the uncertainty of just what transportation means in the Trump administration. Trump promised during his campaign and in his February address to Congress that he plans to launch a $1 trillion infrastructure program, music to the ears of transportation officials and advocates. But Osborne cautioned not to start spending the money just yet.

State Sen. Harriette Chandler of Worcester and state Rep. William “Smitty” Pignatelli of Lenox have introduced bills in the Legislature to create a new practitioner called “dental therapists,” a highly trained dental hygienist who can perform basic procedures such as fillings, simple extractions of non-impacted teeth, and x-ray readings.

Dr. Ray Martin, president of the dental society and a dentist with a private practice in Mansfield, joined The Codcast to talk about the measure along with One-time gubernatorial candidate Dr. Don Berwick, a pediatrician who was administrator for the Centers for Medicare and Medicaid Services in the Obama administration.

Most transportation advocates focus on the need for more money, but Chuck Marohn comes from a different starting point, asking why the system needs more money in the first place. The one thing Republicans and Democrats in Washington seem to agree on is that the country should invest in its infrastructure. But Marohn asks why the nation’s infrastructure, and particularly its transportation infrastructure, has been allowed to deteriorate so badly?

Marohn, the founder and president of Minnesota-based Strong Towns, says that all too often infrastructure gets built with little or no thought as to how it will be maintained down the road.

Today’s Codcast was produced by TransitMatters, the transportation advocacy group, in conjunction with CommonWealth. Marohn was interviewed by Josh Fairchild and Jim Aloisi of TransitMatters.

In what may be a precursor to a soon-to-come Beacon Hill debate on the Pacheco Law, state Auditor Suzanne Bump squared off with Greg Sullivan, research director at the right-leaning Pioneer Institute, to discuss (sometimes heatedly) the pros and cons of the law that regulates privatization of state services.

It was one thing when Sydney Chaffee was named Massachusetts Teacher of the Year. Now she’s been named one of four finalists for National Teacher of the Year, with announcement of the winner due in April.

The Codcast sat down with Chaffee and asked what she thinks makes for great teaching. The two top ingredients, she says, are a passion for what you’re teaching (she says she has that in abundance for the interdisciplinary study of history and English that is her focus) and building relationships with students to see them “as whole people,” gain their trust, and motivate them to take risks. I’m “really trying to fire them up,” she says.
