Last week I casually urged an investigation of ‘Plaza-gate,’ as the Herald pundits are now calling it. But appealing to President Trump to investigate the highway-plaza controversy now engulfing MassDOT, as Howie Carr writes this morning? I think it’s safe to say Trump groupies would take a guilty-as-charged approach to any probe and merely unite the hacks on Beacon Hill. Then again, who else could investigate this mess? Andrea Campbell? … In case you’re wondering, here’s a good ‘BUR summary of Plaza-gate, which recently reached a new low when the “winning” highway plaza-redevelopment bidder suddenly dropped out of the project. …

My hunch is this is more about gross mismanagement than it is about outright corruption. It’s hard not to jump to that conclusion when you think of who’s running the show at DOT (“Has the state transportation secretary been benched?”— Globe. “Some believe Monica Tibbits-Nutt has lost her voice as transportation secretary. Can she find it again?” — Globe). … And, oh, Suffolk Construction is involved. Of course.
