Now that the Legislature's fiscal 2016 budget is on Gov. Charlie Baker's desk, Beacon Hill leaders are struggling to name policy areas they'd like to tackle before enjoying a summer break free of lawmaking.

Since House and Senate negotiators dealt with the year's biggest policy issue in the budget bill itself by including reforms to the MBTA in the annual spending plan, there isn't a whole lot left for the 200 elected legislators to get across the finish line between now and the beginning of their summer recess at the end of the month.

With the heavy lifting of the MBTA reforms out of the way, House Speaker Robert DeLeo is focusing on less controversial items like the ineluctable sales tax holiday. The annual weekend off from the state's 6.25 percent sales tax causes state coffers to take a hit, but people like it so much, even liberal lawmakers chose to live dangerously every year, a little more like our northern neighbors in sales-tax-free New Hampshire.

"I think it would obviously be the sales tax holiday. We may be … We're taking a look at some other legislation which I don't want to mention yet because I'm not sure if it's going forward. But I think primarily the sales tax holiday," DeLeo said to reporters Monday after meeting with Senate President Stan Rosenberg and Baker. Rosenberg, for his part, was also coy about what else may percolate out of the Legislature's not-so-smoke-filled back rooms.

"Hopefully we'll move a few pieces of legislation as well," in addition to closing the books on fiscal year 2015, Rosenberg said.

Legislative committees got off to a slow start this session due to a delayed budget season and a protracted tiff between the House and Senate over the flow of bills through the two chambers. The committees are only now, in the last few weeks of July, truly getting to up to full speed hearing the thousands of bills lawmakers filed earlier in the year.

There's still some work to be done crossing the Ts and dotting the lowercase Js on this year's budget as well, if Baker chooses to exercise his veto powers on any of the extensive bill.

"We'll see exactly what the governor may come out with relative to the budget, relative to vetoes. I would suspect there probably won't be many vetoes. If any, actually," DeLeo said to reporters Monday after meeting with Rosenberg and Baker.

"Because the budget was so good, there's no reason for a lot of vetoes. We'll also start thinking about the final deficiency budget during these few weeks as well," Rosenberg added.

And what of the third member of Beacon Hill's 'Big Three' triumvirate, the impossibly popular (in the polls at least) Baker? Most of Baker's big policy asks were included in the budget's MBTA fix, but a first-term executive could perhaps launch a new legislative campaign springing from months of campaign promises after getting his house in order.

The governor did recently file a hydropower bill that will take some time for lawmakers to mull over, so don't expect much energy legislation to move until the General Court returns to action in the fall.

Then there's Baker's opiate task force report, released almost a month ago with the promise that a bill would follow to put many of the report's recommendations in motion. Baker foresaw legislation in the about ten days from the June 22 release on the report on how to curb the opioid epidemic, but not such bill has surfaced from Team Baker as of yet.
