Behold the making of a possible gubernatorial candidate.

It is Diana DiZoglio, 41, the state auditor and a potential Democratic challenger to Gov. Maura Healey in 2026.

Hollywood screenwriters could not come up with a better script — a lone woman on Beacon Hill standing up to everybody else — Gov. Maura Healey, Attorney General Andrea Campbell, the House and the Senate over two major issues.

One issue is the auditing of the Massachusetts Legislature, of which the voting public approved and which Senate President Karen Spilka, House Speaker Ron Mariano and just about everyone else on Beacon Hill opposes.

The other is DiZoglio blowing the whistle on Healey’s policy of punishing communities that refuse to comply with the MBTA Communities Act which forces them to build multi-family housing near MBTA transit sites.

The two issues, along with illegal immigration, are at the forefront of all the problems facing state government, and DiZoglio is the leading political player on both.

And if challenging Healey is not on DiZoglio’s agenda, it is certainly on the minds of others.

Senate President Spilka, in a jab at DiZoglio at Sunday’s St. Patrick’s Day luncheon in South Boston, brought it up when mentioning possible challengers to Healey. Spilka said, “There might be an auditor in there too.”

Those potential challengers include justice reform advocate Andrea James of Dorchester, a Democrat, while three Republicans have also expressed interest in taking Healey on. They are state Sen. Peter Durant of Spencer, Mike Kennealy of Lexington, a former cabinet member in the Baker administration, and Brian Shortsleeve, a former MBTA official.

DiZoglio, a Democrat, served terms in both branches of the Legislature, where she frequently challenged the Democrat leadership over transparency and accountability, before she was elected auditor in the last election.

Back then House Speaker House Bob DiLeo was happy to get DiZoglio out of his hair when she ran for the Senate in 2018. Four years later Spilka felt the same way when DiZoglio, after two terms in the Senate, ran for state auditor in 2022.

Now they would like to see her out of the State House as well, which could happen if she ran for governor and lost to Healey in the 2026 Democratic primary. But there would be hell to pay if she won the primary and was elected.

If the leading politicos on Beacon Hill think they have a problem with the maverick DiZoglio now, things would be worse if she, an admitted outsider and longshot, were elected governor.

This is not to say that DiZoglio would challenge Healey even though she has two burning issues to run on. At this point in her career, it just might be an office too far.

But it plays into the hands of her opponents who frame her as an ambitious politician who is using the auditor’s office as a steppingstone to higher office.

As things stand now DiZoglio is involved in a tangled web of political and legal battles with the Healey administration, Campbell, Spilka and Mariano over the MBTA housing initiative and the auditing of the Legislature.

DiZoglio has objected to Healey’s practice of withholding state funds from communities that have rejected compliance with the MBTA housing act while rewarding those who do. She called the distribution of funds “an unfunded mandate” since the Legislature did not appropriate the funds.

This has pitted DiZoglio against Healey and Campbell who believe DiZoglio is wrong.

DiZoglio is also in a quarrel with Campbell, Spilka and Mariano over auditing the Legislature, which the legislators oppose even though voters approved it by a wide margin, arguing that it is a separate branch of government that audits itself.

DiZoglio wants to take the issue to court, but Campbell, who ordinarily would represent the auditor’s office, has declined to do so.

So, what’s a frustrated state auditor to do?

Run for governor.
