Following is a roundup of political news reported by State House News Service staff members:

Wu, Gomez, Vargas Back Arroyo for DA: Suffolk District Attorney hopeful Ricardo Arroyo picked up important support on Monday from Mayor Wu, who called him “the last line of defense” in a system known for kts unjustness. Last week, he announced support from two more state lawmakers, as his campaign touted new endorsements from “BIPOC leaders representing communities from across the Commonwealth.” The four are Haverhill Rep. Andy Vargas, Springfield Sen. Adam Gomez, Cape Verdean Social Workers Association founder Carla Monteiro, and Conan Harris, who has worked as executive director of My Brother’s Keeper and held a public safety role in Boston City Hall. Harris is also the husband of US Rep. Ayanna Pressley, and Monteiro was a candidate in last year’s Boston City Council race. Arroyo, a current city councilor, has previously announced support from a handful of Suffolk County lawmakers: Sens. Sonia Chang-Díaz and Sal DiDomenico, and Reps. Russell Holmes, Nika Elugardo and Jon Santiago.

Poll: Dems lead in hypothetical governor match-upUps: Democrats had the edge among voters in each of four hypothetical gubernatorial matchups floated in a new poll. Emerson College Polling surveyed 848 registered voters between May 2 and May 4 and asked about possible face-offs between the top two candidates on either side: Democrats Attorney General Maura Healey and Sen. Sonia Chang-Díaz, and Republicans former Rep. Geoff Diehl and businessman Chris Doughty. If voters had to choose between Healey and Diehl, each of whom is leading their respective primary in the polls, 59 percent said they would pick Healey and 31 percent said they would back Diehl. Against Doughty, Healey still maintained a lead with 54 percent compared to his 31 percent. Voters were more likely to back Chang-Díaz over a Republican, but with lower levels of support than Healey: in a Chang-Díaz-Diehl race, about 46 percent of those polled backed the Democrat and 32 percent backed the Republican, while Chang-Díaz led Doughty nearly 41 percent to 33 percent.

Baker on fellow Republicans: “Let’s see what happens”: While he has clashed with other members of his party in recent years and drawn the ire of former President Donald Trump, Gov. Baker has long insisted he still believes in the Republican Party. But with election season underway, Baker›s latest outlook on the GOP does not exactly sound like a ringing endorsement. «Let›s see what happens between now and November,» Baker replied when asked by WCVB host Janet Wu how much hope he holds for the Republican Party in the near future. «There›s a lot of elections that are going to be held between now and November.” Baker, the top elected Republican in Massachusetts who for years has enjoyed popularity among independents and Democrats, again sought to tamp down the idea that Trump or his allies – like GOP gubernatorial candidate Geoff Diehl – played a role in his choice not to seek reelection to a third term. “This was 100 percent a family decision,” Baker said in an “On the Record” appearance that aired Sunday.
