Gov. Charlie Baker was three-for-three canvassing for the charter school ballot question in Dorchester on Tuesday when he met Ingrid Beckles on her front porch.

Beckles, who said she was surprised to see the governor at her door, later told reporters she wanted “equal opportunities for all kids” including those in district schools, asking, “Why can’t we make all the schools equal? By another week or so I’ll be closer to my decision,” she said.

A major backer of Question 2, which would expand charter school access, the governor received firm commitments at the first three houses he visited Tuesday afternoon before getting Beckles’s demurrer.

Approval of the ballot question would allow the state Board of Elementary and Secondary Education to approve up to 12 new charter schools or enrollment expansions in existing charter schools each year, outside of the existing statutory caps.

Supporters argue the charter expansion would meet a demonstrated demand, especially from areas where district schools are lagging, while opponents argue expansion would sap funding from school districts that serve the majority of public school students.

Nicole Smith told the governor that her children had graduated from Match charter schools and she is taking Match Beyond continuing education. “Match Beyond is really cool,” Baker exclaimed.

Before heading out for his canvassing the governor fired up a crowd of supporters, likening charter schools to a medication that no one would dare deny the public.

“They are a proven success, educating for the most part kids in school districts and in school systems that have underperformed for years,” Baker said. “And in fact they have been in many cases the single biggest thing that have closed the achievement gap between white students and Hispanic students and African American students here in the Commonwealth of Mass. Those are the facts.”

Saying it is “merciful” that the election is only two weeks away, the Republican governor said he and Lt. Gov. Karyn Polito have been busy supporting candidates and will keep up the campaigning in the lead-up to Nov. 8.

“Karyn Polito and I have done somewhere between 80 and 90 events so far for candidates running for office over the course of the past year,” said Baker, who is not supporting any candidate in the presidential race. “We will both be out there campaigning for candidates and we’ll both be out there working on these questions.”

Baker has also been active opposing Question 4, which would legalize adult use and eventually the retail sale of marijuana. The governor, who appeared in a new Question 2 ad Tuesday, said he has no plans to appear in an anti-marijuana-legalization ad.

Along Woodrow Avenue outside Codman Square, Baker encouraged residents to take advantage of the early voting period, open from Monday through Nov. 4.

Beckles, a Democrat who is originally from Trinidad and Tobago, said she wished she had “understood the system” when her daughter attended Boston Public Schools years ago. Saying she is also undecided on marijuana legalization, Beckles said she thinks Baker is “doing wonderful work” as governor.

Though Baker might not have persuaded Beckles to join him in casting a ballot for Question 2, he clearly left an impression. “As soon as I get inside I’ll be calling everybody I know to tell them I met the governor,” she said.
