Emails between a top aide and an ally of N.J. Gov. Chris Christie imply that lane closures along a heavily-traveled bridge between Manhattan and the Garden State — specifically, the area of Fort Lee — suggest the move was political, as the Republican governor’s political rivals have long thought. Christie has, in the past, labeled the shut-down a traffic problem. Fort Lee’s mayor, a Democrat, refused to endorse the governor’s reelection campaign. And it’s not just a local spat when the governor involved is considered a GOP presidential front-runner.
