Scott Brown’s sabbatical from electoral politics shows that he still has much to learn if he aspires to sit in the Corner Office.

His meteoric rise to national prominence sent Republicans into paroxysms of glee, but it also confounded many in Massachusetts. That Martha Coakley ran a poor campaign has become a local truism. Yet Brown got his own comeuppance, when a better candidate, in the person of Elizabeth Warren, came along and plucked holes in the narrative of his short, sweet tenure in the US Senate.

For his part, Brown continually hammered one note: Warren’s Native American heritage. But even as it became clear that voters had wearied of his attacks on Warren’s background, he refused to move on.

Refusing to move on is a problem for the former US senator. Case in point: Bqhatevwr.

Not content with letting his tweets die a quiet death, this latest “pocket tweet” gaffe has prolonged his agony and made him the butt of jokes from coast-to-coast. The man who created Twitter’s iPhone app says Scott Brown’s explanation for a recent spree of late-night tweeting — Brown shot off “whatever,” “whatever bud,” “Your brilliant Matt” and “bqhatevwr” in quick succession, then blamed the utterances on pocket-tweeting — is almost certainly a terrible lie.

A Boston Globe editorial brushes off Brown’s remarks as the foibles of a “tech-shy parent.” However, the story generated no less than three separate Washington Post posts, and Gizmodo, which bills itself as the “go-to authority for gadget news and digital culture” simply eviscerated his explanation, a “Really, Scott?” moment if there ever was one. Blue Mass Group was also less generous, with one commenter comparing the episode to the notorious “secret meetings with kings and queens” incident.

Instead of looking to a former colleague like Florida Sen. Marco Rubio who skillfully navigated his ill-timed water sips into PAC dollars, Brown succeeded in blowing up the almost forgotten tweets again and sending them reverberating around the national echo chamber.

Popular he may be, but an inability to self-censor or turn a gaffe to advantage can quickly cripple a politician. Republicans are already peeved with Brown for bowing out of the Senate special election. As for the governor’s race, next to a seasoned contender like Charlie Baker, Scott Brown will have to work harder to come up with a narrative more substantive than misspelled tweets and tech-newbie fantasies.

BEACON HILL

Former Chelsea housing authority chief Michael McLaughlin pleaded guilty to four felony counts of concealing his inflated salary from federal authorities, and then took a long walk over the Northern Ave. Bridge. McLaughlin has agreed to provide information to federal investigators. A state investigation of alleged illegal political fundraising involving McLaughlin is ongoing. Margery Eagan has a hard time reconciling the deal McLaughlin is likely to get — no jail time if he delivers a Beacon Hill pol to US Attorney Carmen Ortiz — with the prosecutor’s treatment of hacker Aaron Swartz. Eagan is not alone — read the Globe’s letters page for a good sampling of the Ortiz/McLaughlin outrage.
