For Maura Healey and Andrea Campbell, Tuesday’s election was a day to set some markers.

Healey, a South End resident, easily dispatched her Republican opponent for governor to become the first woman, and the first openly gay person, to be elected to sit in the Corner Office at the State House.

Campbell, a Mattapan resident and former Boston City Councillor, trounced her Republican opponent in the race to succeed Healey as attorney general, to become the first Black woman chosen to serve as the state’s chief law enforcement officer and the first Black woman elected statewide in Massachusetts.

Campbell, who defeated Bourne attorney James McMahon, took the stage at the Fairmont Copley Hotel just before 10:30 p.m. to enjoy the celebratory moment. “This moment, this win, our win, is a culmination of hard work, purpose-driven work,” she told the gathering of her supporters, “and I am so ready to get to work on behalf of the commonwealth, on behalf of all of you, as the next attorney general.”

Healey, who beat Geoff Diehl, who was backed by former President Donald Trump, by a hefty margin, told her victory gathering at the Fairmount Copley Hotel that “the people of Massachusetts have given us an historic opportunity tonight, and a mandate to act. We’ll ignore the noise and focus every day on making a difference in their lives.”

She succeeds Charlie Baker, a Republican who decided against running for a third four-year term.

With easy down-ticket wins by incumbent state treasurer Deborah Goldberg and auditor candidate Diana DiZoglio, Democratic women will, come January, hold five of the state’s constitutional offices along with William Galvin, who easily won his eighth term as secretary of state.

Republicans lost major races up and down the Massachusetts ballot, and in Boston, few from the GOP were even on the ballot. Democratic primaries in September appeared to be determinative, as Chris Worrell, a candidate for Fifth Suffolk state representative, beat perennial candidate Roy Owens, who ran as an independent, and Liz Miranda, running for the Second Suffolk state Senate, did not have a Republican opponent.

Healey won Boston with 81 percent of the vote to Diehl’s 17.6 percent. Diehl lost the capital city by roughly 108,000 votes, compared to Baker’s loss in the Democratic stronghold by just 4,000 votes on his way to reelection in 2018.

Campbell, her name recognition high after a 2021 run for mayor, also received 81 percent of the vote in Boston.

During the campaign, McMahon claimed that Campbell was “soft on crime” but his message didn’t appear to resonate with voters in Boston or elsewhere. On Tuesday, the tally at the Lower Mills Library, home to two Ward 17 precincts and Campbell’s voting location, showed her winning,1,125 votes to McMahon’s 195. As results rolled in, she continued to run up similar numbers at other polling locations around the city. At the Savin Hill bellwether, Ward 13 Precinct 10, Campbell won 670 votes to McMahon’s 260.

Polls consistently showed Campbell with a double-digit lead after she won a September primary that included labor attorney Shannon Liss-Riordan, who was backed by US Sen. Elizabeth Warren and top unions, and former Obama administration official Quentin Palfrey.

Campbell, who grew up in Roxbury, leaned on her biography in both the primary and the general election, pointing to a father and two brothers who were in and out of the prison system. Other relatives and teachers supported her as she graduated from Boston Latin School and Princeton University and earned a law degree at UCLA Law School.

After working for Gov. Deval Patrick as deputy general counsel, she was elected to the 13-member City Council in 2015, ousting 30-year incumbent Charles Yancey from the District 4 seat. In 2021, she fell short in the mayoral preliminary, losing to Council colleagues Michelle Wu and Annissa Essaibi George before setting up her run for attorney general. Her campaign platform in the race included ending sentences of life without parole and eliminating disproportionate incarceration of people of color.

Following are other results from the 2022 midterms in Massachusetts.

Lieutenant Governor: Kim Driscoll, the daughter of an immigrant from Trinidad and a Navy cook from Lynn, beat former state representative Leah Allen, who ran on the GOP ticket with Diehl.

Secretary of State: Galvin, of Boston, who was first elected to the post in 1995, handily defeated Whitman Republican Rayla Campbell and third candidate Juan Sanchez.

Treasurer: Deborah Goldberg won reelection easily against Republican Cristina Crawford.

Auditor: Diana DiZoglio, a state senator from Methuen, made it past Winchester Republican Anthony Amore, head of security at the Gardner Museum. In Boston, DiZoglio won 70.22 percent of the vote to Amore’s 21.82 percent.

Congress (7th and 8th Districts): Boston’s two Democratic representatives on Capitol Hill, Ayanna Pressley and Stephen Lynch, easily retained their seats after facing challenges from Republicans Donnie Palmer and Robert Burke, respectively. A twice-unsuccessful candidate for Boston City Council, Palmer in particular spent his Congressional campaign spreading conspiracy theories and asking for votes in Revere, an area that is not within Pressley’s district. With 94 percent of votes counted, the Associated Press called the race for Pressley at 11:14 p.m., putting her at 84.9 percent to Palmer’s 15.1 percent. Lynch saw 69.6 percent of the vote to Burke’s 30.4 percent, with 66 percent of votes counted.

Question 1 (Millionaires tax): The outcome, in the early morning hours after polls had closed, appeared on the way to establishing an additional 4 percent state income tax on annual income in excess of $1 million.

Question 2 (New regulations on dental insurers): Voters enthusiastically signed off on the proposal to regulate dental insurance rates, with the Associated Press calling the race with 58 percent of the votes in. Some 71 percent voted in favor, while 28.5 percent said “no.”

Question 3 (Alcohol sales licensing): Voters appeared on track to reject the ballot question that would have increased the statewide limits on the combined number of licenses for sale that any one retailer could own or control.

Question 4 (Driver’s licenses for undocumented immigrants): A “yes” vote would keep in place a law allowing undocumented immigrants to apply for the licenses. As the night wore on, numbers were showing that the “yes” ballots had the lead.
