Don’t look now but our acting governor this week is Kim Driscoll, the understudy who was supposed to be a key part of Gov. Maura Healey’s administration.

Driscoll so far has turned out to be an adequate functionary and stand-in the way most lieutenant governors are destined to be. Not a powerhouse.

Don’t expect Driscoll, the former Salem mayor, to go rogue this week while Healey is out of the country on a junket to Ireland. No surprise vetoes or late-night budget maneuvers.

She will be quiet and do what Healey wants her to do, which is not much.

Despite the hype about Driscoll when she was hand-picked by Healey, she has no statewide elective experience. Running a small city like Salem and keeping order during Halloween is not the same.

She’s not ready for prime time so she shouldn’t touch anything major. Don’t get too used to that Corner Office.

Stick to signing proclamations or running the Governor’s Council meetings.

The fact is that nobody elected Driscoll to be governor, and she should remember that. Lieutenant governor is a made-up job, it doesn’t really have any function. Massachusetts has gotten by for years without having a lieutenant governor.

And there was never any real expectation Driscoll would be a co-governor like former Gov. Paul Cellucci, who was Bill Weld’s second in command. Cellucci was given real duties by Weld, which served him well when it was time to run for governor.

Most lieutenant governors have been more in the mold of Kerry Healey, Mitt Romney’s second in command who was frequently acting governor but never had any real duties.

Maura Healey was the attorney general, an eight-year state office holder. Driscoll was elected by the few thousand who showed up to vote in Salem.

Despite that, Healey has included Driscoll on important press conferences and meetings, giving her the appearance that she’s useful.

And already Healey seems to have the out-of-state bug that afflicted so many Massachusetts governors before her, like Weld, Mitt Romney, Cellucci and Deval Patrick.

This is Healey’s first foreign junket but it probably won’t be her last. Expect her to be traveling outside the country again, and definitely out of state to locales like Washington, D.C., where she has already been several times.

That will give Driscoll even more experience as acting governor. But it’s not the big time.
