KATHLEEN KANE is an Invader.

Well, technically she's an Invader alumna.

She was a cheerleader for the West Scranton High School Invaders. Oh, and a member of the National Honor Society.

Tuesday, she invades again when she stands in the Capitol Rotunda to be sworn in as attorney general, the first woman and first Democrat elected to the post.

Arguably, she then becomes the most powerful elected woman in Pennsylvania history - if you believe, as I do, that an attorney general has more clout than a state judge, a congresswoman, a state treasurer, auditor general or lieutenant governor.

(Pennsylvania, with one of the nation's lowest percentages of women in elective office, has never had a female governor or senator.)

Here's some idea of who Kane is and what she faces:

Kathleen Margaret Granahan grew up in Scranton's West Side neighborhood in a rented half-a-double. There were four kids, one bathroom. Both parents worked various jobs, including janitor, convenience-store manager and car-dealer secretary.

Kane's brothers, Mark and Joe, are teachers; her twin sister, Ellen, is a deputy state attorney general in Wilkes-Barre and Allentown, a job that she's held for several years.

Kane's a University of Scranton grad with a Temple Law degree. Before becoming an assistant Lackawanna County district attorney, she was at the Philly firm Post & Schell.

She married wealthy Scranton biz-guy Chris Kane (trucking and warehousing); they have two sons, ages 10 and 11.

Politically, she was 2012's total package: Her husband's money and Bill Clinton's endorsement (she worked Hillary's '08 primary); a Democrat in a year when Democrats did well statewide; a pledge to investigate Gov. Corbett's handling of Jerry Sandusky; and a woman running while Republicans angered women by talking about rape and contraception.

She got 3.1 million votes, more than anyone, including Obama.

In short, she invaded the upper political class.

Now what?

She faces delivering on her Sandusky probe, which she plans to begin at once, assigning a full-time, in-house attorney to do nothing but.

She concedes that she has no idea how long it might take, but says, "I will guarantee you this - it will be done in a timely manner."

Asked about Corbett's suggestion that she hire outside counsel for the job, she says: "I'm quite capable of conducting an investigation."

Speaking of Corbett, she read his NCAA lawsuit but won't comment on it because "my personal opinion doesn't matter" and the A.G. has no jurisdiction.

She takes office amid a debate on gun control in a state famous for opposing same. She thinks "assault weapons" and megaclip ammo should be banned, and plans to meet with legislative leaders on the issue.

Asked if she has an opinion on allowing Philadelphia to enact its own gun laws, Kane says, "I don't, just yet."

In an unrelated area, she has a delicate personnel situation.

Her pick for top assistant, Adrian King, Jr., is a former deputy chief of staff to Gov. Ed Rendell.

As my Daily News colleague Chris Brennan reported Friday, King met and dated Kane in law school (and worked with Kane at Post & Shell).

And King's brother-in-law, John Estey, a former chief of staff to Rendell, is now an attorney for the Hershey Trust, which is under investigation by the A.G.'s office.

This is a dicey situation. Candidate Kane railed against Harrisburg's "old-boys' network" and hit her GOP opponent, Cumberland County D.A. Dave Freed, for potential conflict in the Hershey probe, because Freed's father-in-law headed the Hershey Trust.

Now, Kane says that King isn't one of the "old boys" and will be "completely" separated from the trust investigation.

So, we have a good personal story and good political timing helping Kane into high office; and now a full plate of issues and possible pitfalls to determine whether her "invasion" ends up being anything to cheer about.
